Hello. It is probably too late and can not get any refund for this delivery, but a word of explanation is necessary. I order my supplies well before out! So I always have a little 'stock' supplies not to fall down. So I come today, Tuesday, 26.05.2015, open 2 package "cartridges" ink. And it is at that moment that I realized that the reference was not good! Indeed, I ordered an Epson printer cartridges (ref. T0801 and T0807) and those which have been delivered to me bear the references (T0891, T0892 and T0894!). And of course I opened the packages except the T0891! It is true that I should check it out! Shame! But until now I have never had any problems in ordering through Amazon!
