"Which one is actually cheaper" is the wrong first question to ask about GoodRx Companion and Cost Plus Drugs, because they aren't built to do the same job. One is a membership that shaves dollars off a price you pay at the counter of a pharmacy you already walk into. The other is a pharmacy in its own right — one that ships you the medication instead of handing it over a counter, and prices it using a formula it publishes openly. Once you see them as two different tools rather than two competing subscriptions, the decision gets a lot more concrete: it comes down to your specific drugs, how fast you need them, and whether you can plan a few days ahead.
1. What Each Service Actually Is
GoodRx Companion is the current paid membership tier from GoodRx, the company that also runs the free discount-card platform most people already recognize. Companion adds a defined list of free generic medications, deeper discounts on hundreds more, and extras like discounted telehealth, dental, vision, lab, and imaging services. It doesn't dispense anything itself — you still walk into a retail pharmacy like CVS, Walgreens, Kroger, or a local independent, and Companion pricing is applied at checkout instead of your insurance or the free coupon price.
Cost Plus Drugs — officially the Mark Cuban Cost Plus Drug Company — is a licensed online pharmacy, not a discount card. It buys generic medications directly, discloses what it pays, adds a flat and transparent markup, and ships the medication straight to your door. There's no card to show anyone and no pharmacy counter involved on your end, because Cost Plus Drugs is the pharmacy. It launched in January 2022 and built its own dispensing and manufacturing operation in Dallas, Texas, to keep the supply chain short.
The practical distinction: Companion changes the price at a pharmacy you already use. Cost Plus Drugs replaces that pharmacy entirely for the specific drugs it carries.
2. Timeline: How Both Got Here
Cost Plus Drugs launches
Mark Cuban's company opens for business with a small initial catalog of generics, promising to publish its acquisition cost and add a fixed, transparent markup instead of relying on rebate-driven pharmacy benefit manager pricing.
Dallas manufacturing facility opens
Cost Plus Drugs opens its own manufacturing site to produce select medications directly, aiming to shorten the supply chain further and address shortages of certain generics.
GoodRx retires Gold, launches Companion
GoodRx replaces its long-running Gold membership with GoodRx Companion, raising the monthly price but adding a free-medication list and new discount categories. See the full breakdown in our GoodRx Gold vs. Companion guide.
Employer and health-plan partnerships expand
Cost Plus Drugs begins working directly with self-insured employers and health plans to route pharmacy benefits through its pricing model, on top of its direct-to-consumer website.
Two very different tools, same goal
Both companies are now mature, widely used options for cash-pay prescription savings — one built around a physical pharmacy visit, the other built around mail delivery.
3. Pricing Formulas Side-by-Side
| Detail | GoodRx Companion | Cost Plus Drugs |
|---|---|---|
| Membership fee | $14.99/mo ($9.99/mo annual) | $0 — none |
| Pricing formula | Negotiated discount off cash price; some drugs free | Manufacturer cost + 15% + flat dispensing fee |
| Shipping/dispensing fee | None — pick up in person | Flat dispensing fee + flat shipping fee per order |
| Where you get the drug | Local retail pharmacy | By mail from Cost Plus's own pharmacy |
| Insurance usable instead? | Yes, choose per fill | No — cash pay only, always |
| Free trial | 7 days, new members only | Not applicable — no subscription to trial |
| Cancel anytime | Yes, before renewal date | Nothing to cancel — order only when you need to |
"No membership fee" doesn't mean "no fee at all." Cost Plus Drugs still adds a flat dispensing charge and a flat shipping charge to every order. On a very cheap drug, those fixed costs can add a meaningful percentage to the total — which is why ordering several refills together in one order, rather than one at a time, generally saves money.
4. Real Medication Price Examples
Averages hide a lot. The only way to know which is cheaper for you is to look up your exact drug, dose, and quantity on both platforms. That said, here's how the two tend to compare on medications people search for most:
| Medication (generic, common dose) | GoodRx Companion (approx.) | Cost Plus Drugs (approx.) | Typically cheaper |
|---|---|---|---|
| Metformin 500mg, 90-day supply | Often free on Companion's list | Low single digits to ~$10 | GoodRx (if free-listed) |
| Atorvastatin 20mg, 90-day supply | Often free on Companion's list | Low double digits | GoodRx (if free-listed) |
| Lisinopril 10mg, 90-day supply | Often free on Companion's list | Under $10 | Close — check both |
| Sertraline 50mg, 30-day supply | Discounted, not always free | Often under $10 | Cost Plus, if drug isn't free-listed |
| Specialty oncology generics (e.g., imatinib) | Deep discount, still tens to hundreds | Frequently far lower than retail or GoodRx | Cost Plus, dramatically |
| Insulin (most products) | Available at retail pharmacies | Not available — no cold-chain shipping | GoodRx by default |
The pattern that shows up again and again: if your drug happens to be on Companion's free list, GoodRx wins outright — it's hard to beat $0. If it's not on that list, Cost Plus Drugs' transparent cost-plus pricing frequently undercuts GoodRx's discounted-but-marked-up price, especially on specialty generics where PBM-driven retail pricing tends to be most inflated. For a deeper look at how GoodRx's own free pricing works, see our GoodRx Gold vs. Companion guide; for a side-by-side against another discount platform, see Inside Rx vs. GoodRx.
5. Speed: Same-Day vs. Mail-Order
This is the difference that decides a lot of real-world cases before price ever enters the conversation.
| Step | GoodRx Companion | Cost Plus Drugs |
|---|---|---|
| Order processing | None — walk in with the prescription | Typically a couple of business days |
| Delivery | Immediate, same visit | Additional business days after processing |
| Total time to medication in hand | Same day | Roughly a week, sometimes longer |
| Emergency/urgent fills | Works fine | Not a realistic option |
| Routine, predictable refills | Works, but no cost advantage from speed | Ideal — plan ahead once and stay stocked |
The practical rule of thumb: if you're standing at a pharmacy counter today because you're starting a new medication or you ran out, GoodRx (with or without Companion) is your only realistic option. Cost Plus Drugs works best for medications you take every day, know you'll need again, and can order a week or more before you run out.
6. Medications Each One Covers
Companion's medication access mirrors GoodRx's standard retail network — essentially anything a pharmacy stocks, brand or generic, insured or cash-pay. Cost Plus Drugs is intentionally narrower:
What Cost Plus Drugs generally does not carry: brand-name medications still under patent, Schedule II–V controlled substances (including ADHD medications and most opioid pain medications), and injectable products requiring refrigerated cold-chain shipping — which rules out most insulins and some biologics.
If a controlled substance, a brand-name drug, or insulin is what you're searching for, Cost Plus Drugs simply isn't in the running — GoodRx, insurance, or a manufacturer program is where to look instead. Our insulin savings guide and manufacturer savings card comparison cover exactly those gaps.
7. Eligibility & Income Comparison
Neither service is income-based. Both are open to any adult, regardless of income, insurance status, or medical history — which sets them apart from programs like Medicare Extra Help or manufacturer patient assistance programs, which do require proof of income.
| Requirement | GoodRx Companion | Cost Plus Drugs | Income-based programs |
|---|---|---|---|
| Income limit | None | None | Typically tied to Federal Poverty Level |
| Age requirement | 18+ adult membership | 18+ to hold an account | Varies by program |
| Application/approval | None — instant sign-up | None — instant account creation | Often a multi-week review |
| Prescription required | Yes, at time of fill | Yes, e-prescribed or transferred | Yes, plus income documentation |
| State exclusions | Not sold in Washington state | Ships nationwide; specific drug availability may vary | Varies by state/program |
If you're looking for savings tied to income rather than a subscription or cash-pay pharmacy, start with BenefitsCheckUp or NeedyMeds to screen for programs where income actually qualifies you for deeper assistance.
8. Insurance, Medicare & HSA/FSA Rules
This is one of the sharpest differences between the two, and it trips people up.
| Rule | GoodRx Companion | Cost Plus Drugs |
|---|---|---|
| Accepts commercial insurance | No, but you can choose insurance instead per fill | Never — cash pay only |
| Accepts Medicare/Medicaid | No, but usable alongside your plan per fill | Never accepted directly |
| HSA/FSA card accepted | Yes | Yes |
| Submit for out-of-network reimbursement | Possible via receipt, plan-dependent | Possible via receipt, plan-dependent, not guaranteed |
| Can combine with insurance on the same fill | No — it's one or the other per fill | No — never combinable |
If you're on Medicare and comparing cash-pay options against your Part D plan, our GoodRx vs. insurance guide and the Medicare.gov plan finder are the right starting points before assuming either cash-pay option beats your coverage.
9. Which One Fits Your Situation?
Need it today
New prescription, ran out early, or an acute condition. Mail-order timing simply doesn't work for you right now.
GoodRx / CompanionStable, chronic refills
Same generic, same dose, month after month, and you can order a week ahead of running out.
Cost Plus DrugsMixed medication list
Some drugs are urgent or not carried by Cost Plus, others are routine generics it stocks cheaply.
Split between both10. Step-by-Step: Ordering From Each
Check both prices before you commit
Search your exact drug, dose, and quantity on GoodRx (with and without Companion) and on costplusdrugs.com. Prices on both change, so check at the time you actually need the fill.
For GoodRx Companion: sign up and show your card
Create an account at goodrx.com, choose monthly or annual billing, and use the digital membership card at your pharmacy counter instead of running the fill through insurance.
For Cost Plus Drugs: create a free account
Go to costplusdrugs.com and create an account with your name, shipping address, date of birth, and email — no payment or membership fee required just to browse or create an account.
Get your prescription to Cost Plus Drugs
Have your doctor e-prescribe directly to Cost Plus Drugs, or transfer an existing prescription from another pharmacy for non-controlled medications.
Place your order and wait for shipping
Pay at checkout — the listed price includes the dispensing fee, plus a flat shipping fee added per order. Consolidate multiple refills into one order to spread that shipping fee across more medications.
11. Approval Timelines & Renewal Rules
| Step | GoodRx Companion | Cost Plus Drugs |
|---|---|---|
| Application review | None — instant | None — instant account creation |
| Time to first use | Same day, at the pharmacy | Several business days to delivery |
| Recurring charge | Auto-renews monthly or annually | Only when you place an order |
| Cancellation | Cancel at least 1 day before renewal | Nothing to cancel — just stop ordering |
| Refunds | Generally none after billing | Case-by-case on shipping issues |
12. Break-Even Test: Do the Math on Your Drugs
Skip the averages and run this against your own prescription list.
Companion tends to win when a drug is on its free list or when you need something today. Cost Plus Drugs tends to win on stable, non-controlled generics you can order ahead of time.
Example 1 — Priya, on lisinopril and atorvastatin. Both are commonly free on Companion's list. If those two fills would otherwise cost her $10-$20/month combined even at Cost Plus prices, the $0 price beats any cost-plus formula outright, and Companion's $14.99 fee still pays for itself through the free fills alone.
Example 2 — Marcus, on a specialty generic for a chronic condition. His medication isn't on Companion's free list and carries a real discounted price there. On Cost Plus Drugs, the same generic — priced at manufacturer cost plus 15% — comes in dramatically lower, even after the flat dispensing and shipping fees. He orders a 90-day supply at a time to minimize how often he pays that flat shipping fee.
13. Decision Tree
Most people end up using both — GoodRx for anything urgent or free-listed, Cost Plus Drugs for routine refills of standard generics not on that list.
14. Pros and Cons
GoodRx Companion
- Same-day pickup at a pharmacy you already use
- 200+ medications completely free with a prescription
- Works for controlled substances, brand names, and insulin
- Can compare against insurance on any given fill
- Bundled telehealth, dental, vision, and lab discounts
Cost Plus Drugs
- No membership fee at all — pay only when you order
- Transparent, published pricing formula
- Often cheaper on non-free-listed generics
- Flat shipping fee spreads across a whole order
- No controlled substances, brand names, or cold-chain drugs; several days to arrive
15. Common Mistakes to Avoid
16. Can You Use Both at Once?
Yes, and a lot of people do. There's no rule against holding a GoodRx Companion membership while also ordering routine generics from Cost Plus Drugs. A common approach: keep Companion active for anything urgent, anything controlled, and anything on the free list, and route stable, predictable refills of standard generics through Cost Plus Drugs to take advantage of its lower cost-plus pricing. Neither service requires exclusivity, and switching a given prescription between the two from month to month is entirely normal if prices shift.

| Speed | Same day | Same day | Several business days |
| Free medications | No | 200+ free with Rx | No, but low fixed markup |
| Best for | Occasional, already-cheap fills | Free-listed or urgent meds | Routine generics, planned ahead |

Alternatives worth comparing before you commit
- Manufacturer savings cards — for brand-name drugs like GLP-1 medications, programs run directly by manufacturers such as NovoCare (from Novo Nordisk) or Lilly Cares (from Eli Lilly) typically beat any discount card or cost-plus pharmacy. See our manufacturer savings card comparison.
- Patient assistance programs — income-qualified programs for people without coverage; our patient assistance programs guide walks through eligibility and applications.
- Medicare Part D and Extra Help (LIS) — for Medicare beneficiaries, coverage or a low-income subsidy can beat any cash-pay option on covered drugs; see our Extra Help guide and Medicare.gov.
- Prior authorization help — if insurance is denying a drug rather than pricing it too high in cash, neither GoodRx nor Cost Plus Drugs fixes that; see our prior authorization guide instead.
- A general price checker — before assuming either option is your best price, run your medication through our drug price checker to compare multiple sources at once.
All generic medications sold through Cost Plus Drugs, GoodRx-affiliated pharmacies, or any other licensed U.S. pharmacy must meet the same FDA bioequivalence standards as their brand-name counterparts. You can review how that approval process works directly at FDA.gov.
