How This Guide Was Built
This review is based on the official Cost Plus Drugs website, its pricing pages, a peer-reviewed study in the Annals of Internal Medicine (May 2026), and community reports from patients who use the service. We verified the pricing model, medication catalog size, and three-step ordering process. We did not place a test order — all pricing data comes from the official site and published research. Last verified: August 2026.
What is Cost Plus Drugs?
Cost Plus Drugs is an online pharmacy founded by Mark Cuban that sells 2,200+ generic medications at cash-only prices using a publicly disclosed formula: manufacturer cost plus 15% markup plus flat fees. It ships directly to your door and does not accept insurance, bypassing the pharmacy benefit manager middlemen that inflate traditional drug prices. The full catalog is available on the official medications page.
The company launched in January 2022 with a simple premise: Americans should know what their medications actually cost to manufacture. Instead of the opaque rebates and negotiated rates that dominate the industry, Cost Plus Drugs publishes every component of its pricing. You can see exactly what the manufacturer charges, what markup the pharmacy adds, and what you pay for shipping.
The catalog covers chronic conditions that drive the highest prescription spending: diabetes, heart disease, cancer treatment, mental health, and organ transplant anti-rejection drugs. Because it only sells generics — not brand-name drugs or controlled substances — it targets the category where middleman markups create the most damage to patient wallets.
How does Cost Plus Drugs pricing work?
Every prescription on Cost Plus Drugs follows one formula: manufacturer cost + 15% markup + $5.00 pharmacy labor fee + $5.25 shipping. There are no coupon codes, no negotiated rates, and no price variations by customer. The formula is published on the Cost Plus Drugs homepage, and every medication listing breaks down each component line by line.
Here is the exact pricing breakdown for imatinib 400mg (30-count), straight from the site:
| Cost component | Amount |
|---|---|
| Manufacturer cost | $25.65 |
| 15% markup | $3.85 |
| Pharmacy labor fee | $5.00 |
| Subtotal | $34.50 |
| Shipping | $5.25 |
| Your total | $39.75 |
| Typical retail price | $9,657.30 |
| Your savings | $9,622.80 |
The markup stays at 15% whether you are buying a $4 blood pressure pill or a $200 cancer drug Cost Plus Drugs. This predictability means you can calculate your price before creating an account — a sharp contrast to traditional pharmacies where the same drug can cost wildly different amounts depending on your insurance plan.
How to save money on prescriptions with Cost Plus Drugs
Saving money with Cost Plus Drugs requires three steps: search the catalog for your medication, ask your doctor to send a prescription to their pharmacy partner, and place your order online for home delivery. The process takes about ten minutes of active time and works with any U.S.-licensed prescriber. The official website outlines the full workflow.
Step 1: Search the catalog. Go to costplusdrugs.com and look up your medication by generic name or health condition. With 2,200+ generics available, there is a strong chance yours is listed. You will see the exact price immediately — no account needed to browse.
Step 2: Have your doctor send the prescription. Cost Plus Drugs works with a licensed pharmacy partner that accepts electronic prescriptions. Your doctor sends the prescription the same way they would to any pharmacy. No special paperwork or prior authorization is required.
Step 3: Place your order and wait for delivery. Once the pharmacy receives your prescription, you will get an email to create an account and confirm your order. Shipping typically takes a few business days, which makes this service best suited for maintenance medications rather than urgent fills.
Cost Plus Drugs vs insurance: what the data shows
A peer-reviewed study published in May 2026 in the Annals of Internal Medicine analyzed over 62 million employer insurance prescription claims from 2024 against Cost Plus Drugs cash prices. When patients paid more than $15 out-of-pocket for a generic, Cost Plus Drugs was cheaper approximately 80% of the time. For patients paying over $100 out-of-pocket, the typical insurance cost was roughly $140 versus about $25 through Cost Plus Drugs.
The study, summarized by Penn LDI, identified four therapeutic categories with the largest savings: cancer drugs, mental health medications, heart disease treatments, and organ transplant anti-rejection drugs. These are precisely the prescriptions where insurance copays and coinsurance can reach hundreds of dollars per month.
The research has limitations. It covered only employer-sponsored insurance — not Medicare or Medicaid — and did not compare Cost Plus Drugs against discount services like GoodRx or Amazon Pharmacy. But for the question patients actually ask — “what will I pay?” — the data is clear: for expensive generics, Cost Plus Drugs wins more often than not.
Cost Plus Drugs vs GoodRx vs Amazon Pharmacy
These three services use fundamentally different models to lower drug costs. Cost Plus Drugs is a mail-order pharmacy with published cash prices, GoodRx is a discount coupon aggregator for local pharmacies, and Amazon Pharmacy RxPass is a $5/month subscription for eligible generics available to Prime members. Each fits a different need.
| Feature | Cost Plus Drugs | GoodRx | Amazon Pharmacy RxPass |
|---|---|---|---|
| Model | Mail-order pharmacy, published prices | Discount coupons at 70,000+ local pharmacies | $5/month subscription for eligible generics |
| Delivery | Mail to your door | In-person pickup | Mail to your door |
| Brand-name drugs | No | Yes (with coupons) | No |
| Controlled substances | No | Yes (at local pharmacies) | No |
| Insurance | Not accepted | Not required (cash pay) | Not required (cash pay) |
| Best for | High-cost generics shipped to your door | Immediate pickup or brand-name discounts | Prime members taking multiple generics |

What Cost Plus Drugs does NOT do
Cost Plus Drugs does not accept insurance, does not sell brand-name drugs, does not handle controlled substances, and does not offer same-day pickup. These limitations mean it works best as a supplement to your existing pharmacy, not a full replacement. Check the medications page to confirm your prescription is covered before switching.
- No insurance accepted. Every order is cash-pay. Your purchase will not count toward your deductible or out-of-pocket maximum. For patients with high-deductible plans, the cash price is often still lower than the insurance copay.
- No brand-name drugs. The catalog is exclusively generics — 2,200+ of them. If your doctor prescribes a brand-only medication, you need a different pharmacy.
- No controlled substances. Medications like stimulants, benzodiazepines, and opioids are not available through the service.
- No urgent fills. Shipping takes several business days. For a same-day antibiotic or acute medication, use a local pharmacy instead.
Common mistakes to avoid
The most expensive mistake is assuming Cost Plus Drugs is always cheaper — it is not. For low-cost generics where your copay is under $15, your insurance plan may win. The Annals study found Cost Plus Drugs was cheaper 80% of the time above that threshold, which means insurance won 20% of the time. Always compare before you switch.
- Skipping the price comparison. Check both your insurance copay and the Cost Plus Drugs price before transferring your prescription.
- Not checking the catalog first. Tell your doctor to send the prescription only after you confirm your medication is in the 2,200+ item catalog.
- Canceling your local pharmacy too early. Mail-order delivery takes days. Keep your local pharmacy active until your first Cost Plus Drugs order arrives.
- Ignoring the shipping math. At $5.25 per shipment, ordering a 90-day supply instead of a 30-day supply reduces your per-month shipping cost by two-thirds.
