Wal-Mart and Target should have Pond's Towelettes (5 count) priced for less than or around $1. These are great for travel (hence the name!)
Use the $1.50 coupon Here, Here (IE), and Here (FF) for 6 FREE packs (remember to print twice!) Neither of the coupons exclude trial size!
Some locations will not let you use a coupon valued larger than the actual item - your mileage MAY vary.
