LOL my fiance and I do it too! It never fails, we go to Petsmart for litter, just litter, nothing else we say. On the way to the litter aisle is the toy aisle, and we slow down....we glance side to side, and then glance at each other to make sure the other person didnt see us looking at the toys. Halfway down the aisle one of us breaks, usually him, and says somthing like "You know, I bet the cats would love this..." To which id reply "Yeah but look at this one!!!" And before you know it weve spent $60 on toys and a box of litter.
