The supplied with the printer when you buy original cartridges have been replaced. Priced at about 25, - (incl. Shipping) for 20 cartridges (XL version) and comparison with the price of genuine Epson cartridges I've risked my order. The order arrived promptly (2 days in normal delivery). Supplier pointed out that the first change every 4 cartridges have to be replaced at once (because the printer's software only 4 equal chips accepted). Then, the cartridges can be replaced individually. Print quality is just as good as the original cartridges. Absolute Super offer - highly recommended.
