Free products with coupon stacking
At Rite Aid buy two 4-ounce Cetaphil Cleansing face wash products (I've used this stuff, it's very gentle and effective) for $5.49 each. But first go here to join the Cetaphil club (there's a link at the top right) then in your welcome e-mail take the survey, which will net you a $5 off one Cetaphil product coupon (you can print two).
Combine that with the $2 off one Cetephil coupon in the Rite Aid ad to get two products for free.
At Kmart buy a 3-pack of Orbit gum, which is on sale this week for $10/10. Use this $1/1 coupon from Coupons.com to get a 3-pack for free.
Caveats: prices may vary by region.
