Well we all know the trap here. The ink containers supplied with a new printer are much smaller than the refills. There are often 2 sizes in refills now and can easily trap the unwary into thinking they have a good price when it is the smaller version. Frequent changes in printer design also mean that when your ‘new’ printer fails after a year or two the refills you may have ready will not fit your new machine and will not be returnable to the shop.
I would like to say thanks for this info. I am now a customer of Inkstation, and subscribe to both it and Cartridges Direct. When either has a promotion and I have need for more supplies I compare both. Many thanks Ray, for this info.
