I visited the Pier 1 in Conway last weekend and hit the jackpot! They had a rack full of cool cake themed clearance. I wish I had thought to buy them out, but instead walked away with only one package of tissue paper (see pic). What was I thinking?!
On a different note: If you live in central Arkansas, Greenbrier Supercenter has the BEST selection of cake mixes. I found a Cherry Chip mix today and used it to make another batch of Cool Whip Cookies. They were fabulous!
