    3-year warranty on our own-brand cartridges
    We are proud of our own-brand cartridges, so we’ve made trying them a no-brainer. If within three years of purchase you have any problem whatsoever, we’ll happily offer either a replacement or a refund.
    Returning items is easy—it takes just a few minutes. But our return rate is very low, so you’ll be unlikely to need it.
    We are confident that no other own-brand cartridges are better than ours. They produce vibrant prints with accurate colour densities and dark blacks—and their page yields are as good as the genuines, if not better. Give them a try, and see why our customers love them.
    Our own-brand cartridges are incredibly reliable for three reasons:
    1. We are the UK’s biggest seller of own-brand cartridges, and we have invested a lot in optimising them.
    2. We are dedicated to quality. Every own-brand cartridge is performance-tested before it leaves the factory.
    3. We constantly monitor customer feedback, and quickly resolve any issues.
  • Printer protection guarantee
    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 an own-brand cartridge. This is regardless of how old your printer is. We can afford to offer this because problems are almost unheard of.
    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, the 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.

Product Information

About this product

Pay Less for Your HP21XL Ink Cartridge

The HP 21 ink cartridge is probably one of the most popular and best selling printer cartridges on the market, since it's compatible with so many HP DeskJet, OfficeJet and PSC printers. It's reliable, easy to install and produces brilliant results. It has one flaw however: it doesn't hold as much ink as it could. This where the black HP21XL ink cartridge comes to the rescue - it's a high capacity version so you can print even more of your documents and photos with the same reliable and high quality. Also known as the HP C9351CE, the HP 21XL ink cartridge produces sharp and crisp blacks print after print, and because the HP 21XL cartridge uses HP's patented ink formula, it's super resistant to fade too.

Free Delivery on all HP 21XL Ink

Buying online can sometimes be a bit worrying - after all, how do you know how credible an online company is? We are proud to have an award-winning customer service team and to further reassure you we also offer a full money back guarantee on all our HP21XL ink cartridges. In the rare event you should want to return your HP21XL to us, we have a no-quibbles return policy so you can feel secure. In addition to all this, all our HP 21XL ink cartridge come with free delivery.

    I'm delighted with these HP 21XL cartridge. They are ready for use when required on 10 year old backup printer. installation is simple. The price was really good, great value. Delivery was advertised as next-day and arrived on time. I always use Cartridge Save for my cartridges and I would recommend these cartridges to anyone with this printer.

    What is most important about on line purchases is the quality of service and the quality of product, price not so much as long as it is reasonable. Cartridgesave have got quality of service and a quality product in spades. I won’t be going anywhere else anytime soon.

    Good service fast delivery, but what is wrong with my letter box ? WHY do I have to stay home to sign for delivery? And, despite asking, no price is shown on the invoice making claiming expenses very difficult.

    Great service, next day delivery - but I hate it that you have to stay at home for delivery. What's wrong with the letter box? And dispite my request nowhere does it tell me how much it cost, making claiming expenses difficult. Might need to change supplier. :-(
