I too was very suspicious given the announced price. I was afraid that my EPSON Stylus Photo PX710W totally rejects these cartridges at very low prices. Well no, I was wrong to worry especially because I had to really trust your various comments and "Free Ink Shop." My photos are the same whether with these cartridges than the Epson brand.
Each order includes two packages. One T0801 contains a compatible cartridge (black) and the other a set of six cartridges, namely: T0801 (Black), T0802 (Cyan), T0803 (Magenta), T0804 (Yellow), T0805 (light cyan) and T0806 (light magenta).
