I was looking into buying them but at $11.50 I don't seem to come out ahead. Ex. Peco bills: me - chicken wrap $7.39 drink $ 1.99 total w/tax aprox. $ 10.00 so if I added desert I would come out ahead but I normally would not order desert. DH would have cheeseburger and that still doesn't come out cheaper unless desert. So these vouchers are cheaper only if you normally eat desert with your meal??
