Why the same Rifaximin costs $273 at one pharmacy and $780 at another
It's the same FDA-approved rifaximin from the same wholesalers, sitting on different pharmacy shelves with vastly different markups. The price spread on Rifaximin between the cheapest and most expensive pharmacy in a typical US city is ~$585 per month — that's $7020/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 Rifaximin?+
It depends on your zip code. In most metros, independent pharmacies on Script Unlock submit the lowest bids for Rifaximin (~$390/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 $273/mo.
Why is Rifaximin 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 Rifaximin, different markup.
Is Walmart or Costco cheaper for Rifaximin?+

Can a compounding pharmacy fill Rifaximin 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 Rifaximin price?+
Because verified pharmacies bid against each other on your specific prescription — there's no "list price" to game. The lowest bid wins.
