There is a super high value coupon for Nestle Toll House Cookie Dough available on their Facebook page under the Ultimate Cookie Swap tab. Fill in your birth date THEN go all the way to the bottom of the page and hit "CONTINUE", then put in your email address and claim your coupon. Take your time, don't rush - there is ALOT of information on this page and the coupon is easy to miss.
Take the coupon to WALMART where Nestle Cookie Dough is priced at $2.50 and SCORE it for JUST $1!!!! I'm sure this coupon will NOT be around for long so grab it while you can ;o).
