Very disappointed !!!! 335

So let me come post a comment as apparently I can not personally contact the seller by email. I bought this "pack" of ink cartridges there a while, but did not need to install it right away ... What has been done there ... In two weeks After about twenty color printing only, there were already more ink cartridges in 3 colors, and it was only the black cartridge that was still full. Normally it is expected to be able to make about 180 color prints with the cartridge pack. I would have done a hundred it would me (in a pinch) hardly bothered ... But! And I made all possible checks. So there you have it-has an error, a problem with this package even in its production? Perhaps this why I got it for a fairly lower price than offered elsewhere, for example in supermarkets. And the same price Amazon had declined for several days. so ...? I thought to make a deal ... I'm disappointed, I have only to buy another pack of cartridges.
