Why Pharmacy Prices Differ So Much
Each pharmacy chain sets its own cash prices independently. Walmart uses a $4/$10 generic program that drastically undercuts competitors on hundreds of common medications. Costco and Sam's Club pharmacy also offer very low prices, even without a warehouse membership for pharmacy visits in most states. CVS and Walgreens tend to charge higher cash prices but are more convenient and widely located.
With a free prescription discount card like the one RxDiff provides, prices at higher-cost pharmacies can drop significantly — often to within a few dollars of the cheapest option. RxDiff shows you the discounted price at every pharmacy near you in a single search, so you never overpay.
