This is my first purchase from this seller. There is a considerable difference in price between the Inktonerstore product and the Hewlett-Packard product. This is the principal factor that influenced my purchase. The website was easy to use, order from, and pay. Inktonerstore effectively communicated the order/shipping status through to delivery. To date, I see no difference in performance and output quality between the Inktonerstore toner cartridge and the Hewlett-Packard toner cartridge. I would purchase from this vendor again and recommend Inktonerstore to others.
