Excellent and efficient service
By Dale T on 3 February 2024
Ordered HP343 cartridge at 3pm and this was delivered by 11am the next day! Unfortunately the cartridge was not accepted by my printer, but within 24hrs I had a replacement. No quibble process, great Royal Mail service (they brought a printed label to my door and picked up the return) and great Cartridge Save service. Would always recommend Cartridge Save, yes for the good value price, but also for the fantastic customer service.

Heartened to see that Catridgesave have fully embraced re-cycling of used cartridges. Well done about time
By Pip Williams on 11 July 2022
Seems to be a genuine HP product. No problems with installation. I can't comment on the cartridge life, as it hasn't been installed for long, but so far so good. Excellent service!
