too expensive, Epson system pushing for consumption and the expenditure

Amazon is unfortunately not very competitive at prices on this product. I found cheaper (12.35 euros). But the Amazon service is still excellent. And again Congratulations Amazon. Just always FLAWLESS and IRREPROCHABLE.
That said, I am very very disappointed by Epson (competitors are probably like ?!): replace the black cartridge (I only of black and white printing) does not return your machine if you have another empty cartridges. The printer works only if ALL CARTRIDGES still have ink. Furthermore, the cartridges are far from empty when the printer indicates that they are empty. And they are emptying VERY quickly. That would be a count of the number of prints by the inserted chips on the cartridges .... In addition, the printer (ESPSON SX 430 W) crashes at the slightest movement and we must start a process of "realignment" that you empty cartridges in 2 times 3 movements. One feels caught in a trap .... I decided that I would spend a single penny more for EPSON. I therefore command premium quality compatible cartridges which currently work. Ordered on Amazon, trusting consumer opinions on the site page, 8 euros for 4 cartridges of 14ml! Compare the 14 euros for ONE Epson cartridge 11.2 ml!
Here is my experience. Hoping it will be contributory ....
