We now have the official word from HP on which barcode is the UPC you need to send in for rebate redemptions: HP UPC_Code_Guidelines

This should help if you have any questions on what to cut out and send in.  This will ensure you get the gift cards or cash back or whatever else HP is giving away for buying original HP toner for your printers. These rebates typically go on every quarter and we keep the most recent rebates on our homepage.

If you are buying HP OEM toner you should also be taking advantage of HP PurchasEdge rewards program (that’s right, this is not double dipping. Both programs are wholly sponsored by HP). This is another rewards program that earns you one point for every $4 spent on toner. Enroll your company by filling out the form on this page. Once you are accepted into the program you can add your PurchasEdge ID to your account with Granite Office Supplies and your points will automatically be added. These points can be redeemed for free printers and other HP products through the HP PurchasEdge website. If your company spends $1,000 or more on toner per year then this program is worthwhile for you.
