Print a coupon for $1/2 Nabisco Chips Ahoy! Cookies. There is no size restriction on this coupon so you can use it on the Go Cups which are often priced around $1 at many stores to get them for only $0.50 each.
You can also print a coupon for $1/1 Oreo Fudge Cremes.
Thanks, Common Sense with Money!
