Rite Aid updated their coupon policy last month (no big changes) but they did make some language confusing.
The policy now states:
Rite Aid accepts Buy One, Get One Free coupons, however only one coupon can be used for each pair of items purchased.
A customer can use one “cents off” coupon (a coupon of fixed value such as $.50, $1.25, etc.) in conjunction with the item they are purchasing on a Buy One, Get One Free promotion (or with a Buy One, Get One Free coupon), although the value of the cents off coupon cannot exceed the selling price of the item.
Customers can use up to two coupons with a Buy One, Get One at a % off promotion, provided the total value of the coupons does not exceed the selling price of the two items combined.
Buy One, Get One Free coupons cannot be used in conjunction with a Buy One, Get One Free or with a Buy One, Get One at a % off promotion.
