Right now Mentos Gum is on sale at Kroger for $1.00 (and possibly Meijer). Go to the coupons.com widget on the left side of this page. When there, look at the top left of that page and type in zip code 60423. Now, you can print a Mentos Gum coupon-remember 2 per computer. I got 8 and my total oop was $0! You can't beat FREE!
