I recently purchased HP 950 & 951 cartridges online. They process was very simple. I found the ink cartridges I needed for my printer selected them and proceeded to checkout. At checkout I applied a coupon I had to the purchase price and the amount of the purchase was immediately adjusted. I also chose store pickup then input my son's name as he was going to be the one picking it up on his way home from work. It was there waiting for my son when he arrived. The whole process went very smoothly with absolutely no hitches whatsoever.
