Coupon Spotting at Dollar Tree ~Hot Doubler @ Grocery Stores! I spotted a .50/1 Keebler Club Crackers coupon (8oz+) on the back of this box of Keebler Club Cheese Bites 3pk at my local Dollar Tree.. and although it doesn't match the size of the box it's on, hold on to it to use at any store that doubles coupons for a HOT $1 off discount (after doubled) It had a long expiration date through View Post
