Have been using Canon Printers for about 25 years, the last one was an MP610 which riently died on us for our business needs,luckly had a brand new Canon MP540 in the stores and started using this, although had several MP610 print cartridges that didn`t fit the MP540, but got in touch with INKREDIBLE and they sent me out 7 multipacks that fitted the 540 easliy, buying in bulk made it more affordable and the delivery was first class as usual. Telephone INKREDIBLE on the Tuesday night for the 540 catridges and the inks were delivered Wednesday afternoon, only had to do without a printer overnight, so i say thanks inkredible for fast delivery service and excellent affordable prices.

These people provide a first class service!\nIf you need to phone them, you speak to a human being.\nTheir inks a very good value, compared to other ink providers.\nPlus, if you change your printer, they will give you a credit for any unused/sealed  ink cartridges (that are with in the use by date) and send you a postage paid returns bag for this purpose.\nI have recommended Inkredible.com to lots of my colleagues.

Just as good as the Canon equivalent at a fraction of the price.\nI use these to print portrait photos.\nWould recommend to everyone who has a printer.\nI can't see the difference between these inks and Canons.
