You can use the coupons as many times as you need and the coupons do not expire!
However, we always recommend you check the coupon price on the website again before refilling so there won't be any surprises when you pick up your prescription. Prices can change from month to month, so it's possible that another pharmacy or coupon may be less expensive the next time you fill.
As prices fluctuate, we sort through all of the available discounts for a particular pharmacy and medication, then we post the discount with the current lowest price. The coupons we list are from several sources and have different codes and prices. To make sure you get the best price, we do recommend printing a new coupon each time you fill or refill a prescription.
