Caution and "eyes on" is it the price comparison:
At the time my order came me the purchase of "Value Pack 540XL / 541XL" expensive to stand, as if I had ordered the ink cartridges on Amazon individually. Even this are Amazon identical items with otherwise trade names (eg. B. Canon High Capacity Ink Cartridge, Canon ink cartridge Canon Original Ink Cartridge, Canon PG-540XL etc.) at different prices on offer. Kindly Amazon has made me after ordering himself pointed out with the obligatory indication of what other buyers this product also bought. So before placing an order it is comparing exactly what offer is just the best. So the customer's disappointment at the end remains spared, as I 8, - to have paid EUR or 20% too much.
