Mounjaro Cost at Sam’s Club in 2026: Real Pricing Breakdown

Introduction

Mounjaro® at Sam’s Club pharmacy runs about $1,025 to $1,075 per month in May 2026 for a 28-day box of four pens. That’s competitive with Costco and roughly $30 to $80 below typical CVS or Walgreens pricing. Sam’s Club Plus members get small additional discounts on some medications through the Sam’s Club Pharmacy savings program, but Mounjaro isn’t typically on that list.

You don’t need a Sam’s Club membership to use the pharmacy. Federal pharmacy law requires Sam’s Club to fill prescriptions for any walk-in customer. The Plus tier ($110/year) adds 5 free generic medications and a small extra discount on some brands, but on a $1,000+ brand drug like Mounjaro, those member perks barely move the price.

This guide breaks down what Mounjaro really costs at Sam’s Club in 2026, when the Lilly savings card applies, and the alternatives most patients are choosing instead.

How Much Does Mounjaro Cost at Sam’s Club Without Insurance in 2026?

Without insurance, Mounjaro at Sam’s Club costs around $1,025 to $1,075 for a 28-day box. That’s a slight discount versus the big drugstore chains because Sam’s Club operates pharmacy on thinner margins. The Lilly list price drives the floor, and Sam’s Club adds a smaller dispensing markup than CVS or Walgreens.

Quick Answer: Mounjaro cash price at Sam’s Club is roughly $1,025 to $1,075 per month

Lilly flat-prices all six Mounjaro doses (2.5 mg, 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg). So whether you’re starting at 2.5 mg or maintaining at 15 mg, you pay the same monthly cash price. That intentional pricing protects diabetes patients during titration.

Annual cash cost at Sam’s Club works out to about $12,300 to $12,900. That’s marginally cheaper than CVS or Walgreens annual cost but still well above what most patients can sustain without insurance support or alternatives.

Do I Need a Sam’s Club Membership to Fill Mounjaro?

No. Federal pharmacy law requires Sam’s Club to serve non-members at the pharmacy. You can walk in, drop off a prescription, and pay at checkout without showing a membership card. Most Sam’s Club locations have a separate pharmacy entrance or path that bypasses membership verification.

The Plus membership ($110/year) bundles small pharmacy benefits like free generic medications and modest brand discounts. For Mounjaro specifically, the discount is negligible because Lilly’s contract terms with retailers limit how much the pharmacy can mark down brand-name GLP-1s.

If you’re using Sam’s Club for other shopping, the membership pays off. If you’re going purely for Mounjaro, paying the cash price as a non-member costs the same as a Plus member rate within a few dollars.

Does the Lilly Mounjaro Savings Card Work at Sam’s Club?

Yes. Sam’s Club pharmacies accept the Lilly Mounjaro Savings Card. With commercial insurance covering Mounjaro for type 2 diabetes, eligible patients pay as little as $25 per month. The card caps total monthly savings at $150, which means it works best when insurance is already paying most of the price.

The card requires a type 2 diabetes diagnosis on the prescription. Patients prescribed Mounjaro off-label for weight loss aren’t eligible. Medicare, Medicaid, TRICARE, and VA patients also can’t use the card due to federal anti-kickback rules.

Without insurance, the savings card brings the price down to about $573 per month at Sam’s Club. That’s a real savings but still high for most patients to sustain long-term.

What Does Mounjaro Cost at Sam’s Club with Insurance?

With commercial insurance covering Mounjaro for type 2 diabetes, Sam’s Club copays typically run $25 to $90 per month. Most commercial plans place Mounjaro on Tier 3 with copay structures varying by plan design. Plans using coinsurance instead of flat copays come out higher, often $150 to $320 monthly.

Stacking the Lilly savings card on commercial insurance is the path to $25 per month. The card pays whatever the insurance leaves behind, up to the monthly $150 cap. This combo is why Sam’s Club ends up as one of the cheapest places for insured diabetes patients to fill Mounjaro.

Medicare Part D plans cover Mounjaro for type 2 diabetes with copays ranging $50 to $400+ depending on the plan tier and whether the patient has crossed the catastrophic coverage threshold (2024 KFF analysis).

Is Mounjaro Covered for Weight Loss at Sam’s Club?

No. Mounjaro is FDA-approved only for type 2 diabetes. Insurance won’t cover it for weight loss at any pharmacy. Patients seeking tirzepatide for obesity should be prescribed Zepbound® (FDA-approved for chronic weight management in November 2023). Both contain the same active ingredient.

The SURMOUNT-1 trial (Jastreboff et al. 2022 NEJM) showed 20.9% mean weight loss at 72 weeks on tirzepatide 15 mg in adults with obesity. That trial drove Zepbound’s approval and is the standard reference for tirzepatide weight-loss efficacy.

Sam’s Club pharmacy will fill any valid Mounjaro prescription. If the indication is off-label weight loss, insurance will deny, and the patient pays the full cash price.

How Does Sam’s Club Pricing Compare to Other Pharmacies in 2026?

Sam’s Club and Costco price Mounjaro nearly identically, usually within $10 to $30 of each other. Both warehouse club pharmacies undercut CVS and Walgreens by $30 to $100 on cash price. Walmart sits between warehouse clubs and major chains. Independent pharmacies vary widely.

For insured patients using the Lilly savings card, the cash-price differences disappear since everyone ends up at $25 monthly. For uninsured cash payers, Sam’s Club, Costco, and Walmart are the best brick-and-mortar options, but none match LillyDirect’s Zepbound vial pricing ($399 to $499) or compounded tirzepatide through telehealth ($199 to $499).

Key Takeaway: Plus membership perks don’t meaningfully reduce Mounjaro pricing

What Are Cheaper Alternatives to Mounjaro at Sam’s Club?

The three primary alternatives in 2026 are Zepbound vials through LillyDirect, compounded tirzepatide through licensed telehealth, and compounded semaglutide. Each has different cost profiles and access considerations.

Zepbound vials shipped from LillyDirect cost $399 (2.5 mg) to $499 (5 mg and higher) per month. The vials require self-drawing into a syringe rather than a prefilled pen, but the active molecule is identical to Mounjaro. Lilly built this self-pay channel in August 2024 to capture cash-paying weight-loss patients.

Compounded tirzepatide narrowed sharply after the FDA declared tirzepatide off the shortage list (October 2024). Some 503A pharmacies still compound under individual medical necessity documentation, with telehealth prices $199 to $499 monthly. Compounded semaglutide remains more available at $179 to $349 per month. TrimRx offers a free assessment quiz to identify which option matches a patient’s medical situation and goals.

Does Sam’s Club Offer Mail-order Mounjaro?

Yes. Sam’s Club Pharmacy Mail Order ships Mounjaro to members and non-members at the same cash price as in-store. Some commercial insurance plans route to Sam’s Club Mail Order with 90-day fills at lower per-month copays.

Cash payers don’t see meaningful savings through mail order because the list price is set by Lilly, not the pharmacy. Insured patients with 90-day fill allowances can sometimes drop copays $5 to $20 per month through mail order.

Mounjaro requires cold-chain refrigerated shipping. Sam’s Club uses overnight delivery for temperature-controlled medications, which means patients need to be home to receive the package or have a way to refrigerate it promptly.

Can I Use HSA or FSA for Mounjaro at Sam’s Club?

Yes, when prescribed for type 2 diabetes. HSA and FSA funds cover prescription drugs, and Sam’s Club pharmacy processes benefits cards at checkout. Pre-tax dollars save 22% to 37% on the purchase depending on your tax bracket.

HSA/FSA coverage for off-label weight loss use depends on documentation. IRS rules require a specific medical indication. Patients with documented obesity (BMI 30+) or weight-related comorbidities can typically use HSA funds with a Letter of Medical Necessity, but the administrator’s approval matters more than the IRS guidance in practice.

Sam’s Club pharmacy receipts list the medication name and prescription details for HSA/FSA documentation purposes.

Will Sam’s Club Have My Mounjaro Dose in Stock?

Most Sam’s Club pharmacies stock the common doses (2.5 mg, 5 mg, 7.5 mg, 10 mg) reliably in 2026. Higher doses (12.5 mg, 15 mg) may need a 1 to 3 day special order. The FDA’s October 2024 resolution of the tirzepatide shortage stabilized supply across all major chains.

Sam’s Club’s smaller pharmacy footprint compared to CVS or Walgreens means fewer locations, but each store typically maintains adequate inventory for routine fills. Calling ahead before driving is a smart move, especially for higher doses.

If your local Sam’s Club is out, the pharmacist can transfer the prescription to another nearby location or order through the chain’s central fulfillment.

How Long Is a Sam’s Club Mounjaro Prescription Valid?

A Mounjaro prescription from a U.S. licensed prescriber is valid for one year from the written date, with up to 5 refills if authorized. Sam’s Club honors transferred prescriptions from other pharmacies and electronic prescriptions sent directly from prescriber offices.

Telehealth prescriptions for Mounjaro work the same as in-person prescriptions at Sam’s Club. As long as the prescriber holds an active license in the patient’s state and the prescription is properly documented, the pharmacy fills it.

Bottom line: Compounded tirzepatide through telehealth runs $199 to $499 per month, well below retail

FAQ

Is Mounjaro Cheaper at Sam’s Club or Walmart?

Sam’s Club typically prices Mounjaro $5 to $30 below Walmart in most regions. Both Walmart and Sam’s Club are owned by Walmart Inc., but Sam’s Club pharmacy operates on slightly thinner margins. The difference is small enough that location convenience usually matters more than the price gap.

Does Sam’s Club Plus Membership Give a Mounjaro Discount?

Not meaningfully. Plus membership offers small discounts on certain brand medications, but Mounjaro pricing is constrained by Lilly’s contract terms. Plus members and non-members pay within a few dollars of the same price for Mounjaro.

Can I Get Mounjaro at Sam’s Club with Medicaid?

Sam’s Club pharmacy accepts state Medicaid when the patient has a covered type 2 diabetes diagnosis and prior authorization. Coverage rules vary by state. No Medicaid program covers Mounjaro for off-label weight loss.

Does Sam’s Club Accept GoodRx for Mounjaro?

Sam’s Club accepts GoodRx coupons, but GoodRx pricing for Mounjaro matches the cash price within a few dollars. Lilly’s contracts prevent third-party discount programs from offering meaningful savings on brand-name GLP-1 medications.

What If Sam’s Club Doesn’t Have My Mounjaro Dose?

Ask the pharmacist to transfer the prescription to a nearby Sam’s Club with stock or to special order through central distribution. Most special orders arrive within 1 to 3 business days. Patients close to running out can sometimes get a partial dispense to bridge.

How Do I Switch From Mounjaro to Compounded Tirzepatide?

A licensed prescriber needs to document medical necessity and write a new prescription routed to a 503A compounding pharmacy. TrimRx offers a free assessment quiz to match patients with a personalized treatment plan and can connect eligible patients with telehealth providers offering compounded options.
