Why the same Metformin costs $2 at one pharmacy and $12 at another
It's the same FDA-approved metformin from the same wholesalers, sitting on different pharmacy shelves with vastly different markups. The price spread on Metformin between the cheapest and most expensive pharmacy in a typical US city is ~$11 per month — that's $132/year for the exact same medication.
Three drivers cause the spread: (1) chain pharmacies use opaque national list prices, (2) independents compete on cash-pay because they have to, and (3) PBM contracts at chains inflate cash prices to protect rebate economics. None of this benefits you. Bidding does.

Frequently Asked Questions
What is the cheapest pharmacy for Metformin?+
It depends on your zip code. In most metros, independent pharmacies on Script Unlock submit the lowest bids for Metformin (~$6/mo), beating CVS, Walgreens, and Rite-Aid by a wide margin. The only reliable way to find the cheapest is to let verified pharmacies bid — current low bids start at $2/mo.
Why is Metformin so much cheaper at one pharmacy than another?+
Three reasons: (1) chain pharmacies use national list prices that include overhead from corporate marketing; (2) independent pharmacies have lower overhead and use cash-pay pricing as a competitive weapon; (3) PBM contracts at chains inflate the published cash price to maintain rebate spreads. Same FDA-approved Metformin, different markup.
Is Walmart or Costco cheaper for Metformin?+
Sometimes. Walmart and Costco have aggressive generic programs that often beat CVS/Walgreens on common drugs like Metformin. But independent pharmacies on Script Unlock typically still come in lower (~$6/mo) because they bid against each other in real time, and you don't need a Costco membership.
Can a compounding pharmacy fill Metformin cheaper?+
Sometimes — particularly if you need a non-standard strength, a different dosage form (capsule vs tablet, liquid vs solid), or a single-ingredient version without unwanted excipients. Compounding pharmacies on Script Unlock bid alongside retail pharmacies so you see all options head-to-head.
How do I know I'm getting the actual cheapest Metformin price?+
Because verified pharmacies bid against each other on your specific prescription — there's no "list price" to game. The lowest bid wins.
