How RxDiff Prices Work
RxDiff shows you real cash prices for prescription medications at nearby pharmacies, so you can compare and find the lowest price before you fill a prescription.
What we use to generate a price:
- Drug name and form — the exact medication, strength, and quantity your prescription calls for
- Your location — pharmacy prices vary by zip code, so we show results near you
- Live pricing data — prices are pulled from participating pharmacy networks and refreshed regularly to reflect current discount card rates
How refreshes work:
Prices can change day to day based on pharmacy and wholesaler updates. We refresh our data regularly, but the price you're quoted online is an estimate — always confirm the final price with the pharmacist at checkout.
What RxDiff can't verify:
We can't guarantee real-time inventory, insurance coordination, or pharmacy-specific promotions that aren't reflected in our data feed. Prices shown are for the discount card / cash-pay price, not insurance copays — if you have insurance, compare your copay against our cash price to see which is lower.
How we make money:
RxDiff is free to use. When you fill a prescription using one of our coupons, the pharmacy or program may pay us a referral fee. This does not change the price you pay, and no pharmacy pays us to be ranked higher in results.
