I found Clean & Clear Foaming Cleanser on clearance for $2.99 today at my Walgreens store. Stack a $1.00 printable manufacturer coupon with a $3.50/2 store coupon from page 18 of the Walgreens September Savings Book. The Clean & Clear manufacturer coupon has a limit of one. When you buy one item and use a $3.50/2 store coupon, the register will automatically apply half of the $3.50 (which is $1.75) to the transaction. Pay just $0.24!
Note: Clearance varies by store.
