How Printholm checks prices

Every price shown is collected manually from each retailer's product page and verified before publishing. We check all 4 retailers for each cartridge family every week and update the comparison tables whenever a price changes.

All prices shown are for compatible (non-OEM) multipacks including VAT. Delivery is included in the total where free. OEM prices are taken from the manufacturer's direct store and used only as a savings benchmark.

Are compatible cartridges safe to use?

Yes. Compatible cartridges use the same ink chemistry as originals and are guaranteed to work in your printer. Under UK consumer law, using compatible ink does not void your printer warranty — HP, Canon, and Epson cannot legally require you to use only their own cartridges.
