My box had both a sticker with the UPC and serial number on it and then it had the UPC like the one pictured from your link. I went ahead and cut out the UPC and included the sticker with the serial and UPC just to be safe. I don't need the hassle of possibly getting denied just because I'm just too lazy to cut off the UPC from the box that is printed on the box.Mine only had the UPC on the box; there was nothing to peel off so that's what I sent in. There's mention on Khypermedia's web site about a 24 digit barcode that may not exist on some boxes. I assume this is the peel-off sticker you have ? See their web site FAQ
BTW.. If your retail box didn't have the sticker, what are you using for a 24 digit serial number bar code?
Thanks.
