It is difficult to comparison shop for HP ink because many of the low prices found online are for ink that is not genuine HP. I have found B&H to have the best price for all the 920XL colors and black. [...]

I have have used the HP 920 double packs for a while, this pack did not last more than a month per cartridge (less than 100 pages). I do not print that much. I normally average 2 months or more per cartridge in the past. I will never order on line from Sam's again.

It is my policy to always use genuine inkjet cartridges for my HP A3 printer. I always purchase them from John Lewis because they are delivered very quickly and the price is always competitive. HP colour inkjet cartridges produce vibrant colour prints and they appear to last a long time.
