Our cartridges won’t damage your printer—guaranteed
Some people worry that own-brand cartridges might damage their printers. We know from experience that ours don’t.
To reassure you, we guarantee that we’ll repair or replace your printer—for free—in the unlikely event that it gets damaged by our own-brand cartridge. This is regardless of how old your printer is. We can afford to offer this as problems are almost unheard of.
Your printer warranty is safe
Some people whose printers are less than a year old worry that an own-brand cartridge might invalidate the manufacturer’s warranty. This isn’t true. By law, manufacturers aren’t allowed to invalidate your warranty if you use own-brand cartridges. If something does go wrong and our own-brand cartridges are to blame, we’ll take over the manufacturer’s warranty, offer you phone support and repair or replace your printer if needed.
In summary there’s zero risk in using our own-brand cartridges.

Have used Cartridgesave for all my toner and ink for several years now, and they are great. Prompt delivery and great price. However for me the really great thing about them is how they deal with the very rare issue I may have with the supplies, they are brilliant. Replacement toner was sent out recently with a Saturday delivery, awesome and really save my bacon. Will always use these guys for my consumables.

There was a problem with one of my cartridges on a recent delivery. There was no way anyone could have known this as it was a sealed unit. Cartridge save sent me a free replacement within 48 hours. No need to send back the damaged one. Fast, efficient service. They've got me as a customer for all my 'home working' needs for life.
