How each works
RxDiff
Search the exact medication, form, strength, quantity, and ZIP code to compare available pharmacy price estimates. Select Get Coupon and show the coupon to the pharmacist before paying. RxDiff is not a pharmacy or healthcare provider.
WellRx
Find the prescribed product and participating pharmacy through ScriptSave WellRx, then show the savings card each time you fill or refill and pay at the register. Recheck the estimate on the day of purchase; prices can change and the pharmacy must process the WellRx card rather than a different discount.
Cost
RxDiff
RxDiff public search is free and requires no account or insurance. A pharmacy's final prescription charge is separate; confirm it before paying.
WellRx
ScriptSave WellRx is free to join and free to use, with no enrollment fee. Website account registration is not required to use the savings card. An optional free account provides additional medication-management tools; no paid membership is required for the verified savings-card service. You pay for your prescription purchases at the pharmacy.
Where accepted
RxDiff
A returned result identifies a pharmacy location. Confirm stock, coupon acceptance, and the final price with that location; availability varies by medication and location.
WellRx
ScriptSave WellRx works at participating chain and independent retail pharmacies found through its prescription price tool. Its FAQ limits discounts to the U.S., Puerto Rico and Guam and to FDA-approved medications. Brand and generic prescriptions may qualify; human-equivalent pet medications require a veterinarian's prescription. Confirm the exact product and location rather than assuming every pharmacy participates.
Who it suits
RxDiff
People comparing pharmacy estimates before filling a prescription. Pill identification and drug interaction tools are also available; they do not replace advice from a pharmacist or doctor.
WellRx
Households comparing brand or generic prescription costs, including people without prescription coverage or checking a medicine not covered by their plan. One card can serve the household, including qualifying pet prescriptions, and website registration is optional. A discount estimate is not a guarantee of stock, a delivered order or a lower price than insurance.
Compare before each fill
Match the medication, brand or generic product, form, strength, quantity, pharmacy, and ZIP code. For shipping options, compare the complete delivered total and fulfillment terms. No current competitor quote or savings percentage is asserted here.
