Prescription drug plan from Walmart and Humana.
Walmart operates one of the largest pharmacy networks in the country, and for people already shopping there, the pharmacy is a convenient, and affordable, place to fill prescriptions. Several different savings programs apply at the Walmart pharmacy counter — some run by Walmart, some by outside companies — and they serve different situations.
This page covers savings available specifically at Walmart and Sam's Club pharmacies. For prescription savings at other pharmacy chains or from non-profits and other sources, see the guide to pharmacy programs for free medications or savings. For free prescription discount cards and apps that work across many pharmacies including Walmart, see the free RX website and appls discount guide.
The $4 generic drug program
Walmart's longest-running pharmacy program offers a list of common generic medications at $4 for a 30-day supply and $10 for a 90-day supply. No membership is required, no insurance is needed, and there is no sign-up. A patient simply brings a valid prescription to the Walmart pharmacy and asks whether their medication is on the program list. If it is, the discounted price applies automatically.
The program covers several hundred generic drugs for common chronic conditions — blood pressure, cholesterol, diabetes, thyroid, mental health, and digestive conditions are among the categories covered. Antibiotics, antihistamines, and steroids are not included. The list is managed by Walmart and can change without notice, so confirming that a specific drug is still on it before transferring a prescription is worth the phone call. Prices may be slightly higher in a small number of states including California and Minnesota. The full current list is at https://www.walmart.com/cp/4-prescriptions/1078664.
The 90-day supply option at $10 is worth noting for anyone on a stable, ongoing prescription — three months of medication for the price of two and a half monthly fills, without a membership or any enrollment.
The program is available at all Walmart and Walmart Neighborhood Market pharmacies nationwide except North Dakota. Sam's Club pharmacies also offer comparable pricing, and a Sam's Club membership is not required to use the pharmacy.
Third-party discount cards at Walmart pharmacy
Walmart does not issue its own universal discount card, but accepts free third-party discount cards and coupons at the pharmacy counter. Services including GoodRx, SingleCare, and ScriptSave WellRx all work at Walmart pharmacies and can sometimes produce prices lower than the $4 list on drugs not included in that program, or lower prices on brand-name drugs that the $4 list does not cover.
The process is the same regardless of which card a patient uses: look up the drug on the service's website or app, get the coupon code, and present it to the pharmacist. The pharmacist will apply whichever price is lowest. A patient cannot combine a discount card with insurance for the same prescription, but comparing the discount card price against the $4 program price for any given drug takes seconds and is worth doing. More detail on GoodRx is on the how to use GoodRx assistance page. The free prescription service discount cards guide covers additional options.
Walmart and the Insurance Company Medicare Part D plan
For many years, Walmart and insurers such as Humana offered a co-branded Medicare Part D prescription drug. While changes have occured over the months and years, the plan itself continues, and Walmart — along with Walmart Neighborhood Market, Sam's Club (no membership required), and a small number of other preferred retailers — remains in the plan's preferred pharmacy network.
What preferred pharmacy status means in practice: Medicare Part D enrollees in this plan pay lower copayments when filling prescriptions at a preferred network pharmacy like Walmart than they would at a non-preferred pharmacy. For a Medicare beneficiary who already shops at Walmart, this can reduce per-prescription out-of-pocket costs compared to filling the same prescription at a pharmacy outside the network.
This is a Medicare Part D plan, which means it is only available to people enrolled in Medicare Part A or Part B. It is not available to the general public without Medicare. Premiums, copayments, and the list of covered drugs vary by location and change each year. Anyone evaluating this plan should compare it against all available Part D options for their ZIP code using the plan comparison tool at https://www.medicare.gov/plan-compare/, not based on prior-year pricing. Or read more information on the NHPB page on how to select Medicare Part D.
Lower-income Medicare enrollees may qualify for the Extra Help program (also called the Low-Income Subsidy), which substantially reduces Part D premiums and copayments regardless of which plan they choose. Information on Extra Help is at https://www.ssa.gov/medicare/part-d-extra-help. We also have a user friendly guide to the Extra Help program.
Walmart+ and pharmacy delivery
Walmart+ is a paid membership program ($12.95 per month or $98 per year as of 2026) that includes free home delivery on prescriptions. Without Walmart+, mail delivery of a 90-day supply of a $4 program medication carries a $10 shipping fee — the same as the cost of the medication. For Walmart+ members, that fee is waived. For a household that fills several ongoing prescriptions and values the convenience of home delivery, the math on membership may work in their favor. Walmart+ also includes free grocery delivery and other benefits unrelated to pharmacy. It is not required to use any of the pharmacy savings programs described above.
A note on using multiple options
These programs do not all overlap cleanly, and the lowest price on any given drug depends on which program applies. For a generic drug on the $4 list, that is usually the cheapest option — but checking a GoodRx or SingleCare price takes thirty seconds and occasionally beats it. For drugs not on the $4 list, a third-party discount card is the next step. For Medicare enrollees, preferred pharmacy copayments through a Part D plan may be lower than any of the above. Asking the pharmacist to compare options is a reasonable thing to do.
