There is a new $5/1 any Bengay product coupon (excludes trial size). You can take this coupon to Walmart and buy the regular Bengay that sells for a little over $4 and get it better than free after coupon. Or print and hold this coupon as these products often go on sale at CVS, Rite Aid or CVS. You will often find them with a +UP Reward, Extra Care Bucks or Register rewards deal. The coupon I just printed expires in 60 days.
