I recently placed an order for a LeapFrog Leapster2 at the LeapFrog Web site using two promo codes. However, my order reflected only one promo code. I didn't find anything on the Web site that said I couldn't use multiple promo codes. As proof, I saved the shopping cart and order confirmation pages as PDFs. I also took a screenshot of the promotion along with its fine print, which says nothing about stacking promo codes.
