You can use and reuse the coupons as often as you like, and they don't expire.
However, we always recommend that you check the coupon price on the website again before refilling so there won't be any surprises when you pick up your prescription. Because the coupon prices are tied to actual cash prices which fluctuate over time, prices can change from month to month.
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 have different sources and codes - so you'll need to be sure you are using the most up-to-date coupon.
To make sure you get the best price, we do recommend printing a new coupon each time you fill or refill a prescription. Then, make sure the pharmacist enters the new coupon codes.
