HP has upped their usual rebate gift card to $40 with the purchase of 3 of the SAME HP Brand cartridges. If you buy HP cartridges and don’t mind filling out a rebate offer, there is almost always an HP rebate out there. This round, the rebate card includes Macy’s, Shell, and Darden Restaurants (Red Lobster, Olive Garden, Long Horn Steakhouse, etc). This offer expires 12/31/2012. Note you have 90 days from the invoice date to file your rebate. Click here to download the HP Rebate form.
