I bought my HP printer from Staples and found it logical to continue buying ink there too. I respect the quality and selection. I am surprised at the extreme rise in prices for ink over the last couple of years. I will be comparison shopping. I live close to Staples so convenience is a factor and I have been doing business for years at Staples so our business relationship is also a factor as well.
I am not sure if it is the ink or the printer which is awful the quality of the printing is no where nearly as good as previous printers I have had. I will not be buying another HP.
