Carmex lip balms are on sale this month at Walgreens, buy one get one free. Use a $1.00/2 coupon from last Sunday’s newspaper to save big! According to the Walgreens coupon policy, a coupon cannot apply to a free item. To comply with the coupon policy, buy four lip balms and use one $1.00/2 coupon. Each lip balm will be $0.55! In my store, the lip balms are on the medicine aisle. They have cherry and strawberry flavored Carmex.
