I don't know how long I have been buying my cartridges from Inkjet Wholesale, but it's been many years. their generic products are second to none. I have never had any problems with the products. They are heaps cheaper than the original brands and last just as long. The delivery times are amazing, mostly within twenty-four to thirty hours from time of order being placed. I recommend their generic inks to all of my friends and they all thank me for the advice. I will always use and recommend Inkjet Wholesale.
