i plan on auctioning off my zombie nation box and manual soon on ebay.. i was going through the manual which excellent condition. on one of the pages there is a small rectangular sticker that says customer above a barcode and then a number... one of the numbers the last one is hand written. it doesn't look like some random person who owned the game put this sticket there but maybe the company that made the game? anyone ever seen one of these in a manual before? i'll attach a pic
