I am happy with the customer service provided by Toner Cartridge Depot. I hoped to order a one-box four-pack of Black, Cyan, Magenta and Yellow cartridges for my laser printer but they were out of stock at the time. Instead I placed an order for a set of three-color (CMY) and a separate black cartridge but the cost was higher since the order consisted of two boxed items instead of one. When I received the shipment it consisted of the lower-cost one-box four-pack of CMYK cartridges. When I notified the Sales department at Toner Cartridge Depot they promptly refunded me the price difference. I plan to order from them again when I need new cartridges. read more
