Do you still have the $1/1 Mentos Gum coupons from the 10/3 Smart Source? I used mine up last week to get free gum at Stop N Shop. If you haven't used them, Walgreens has the Mentos gum on sale for $.99 this week using their in-ad coupon, making them absolutely free (plus a penny, so find a cheap filler if you're not planning on purchasing anything else). There are some other great freebies at Walgreens after Register Rewards and Rebates, including Colgate toothpaste and a variety of cold medicines. Check out Money Saving Mom for a detailed list of this week's Walgreens deals.
Remember, gum is always a great treat for your Operation Christmas Child!
