I can not stand to have me financially, I wish to pay to its fair value. If I had paid full price for a batch of 18 cartridges (6x3), cannon brand I would pay 70.85 x 3 = 212.55. Recently I used a mark of 37.50 in shopping center X 3 = 112,50. With Start-France for 18 cartridge, I paid 15.90 + $ 4.99 shipping fee is, 20.89 euros. And in addition it works very well!
