Non-UK natives beware this company's site and support! I have a US HP printer, ordered ink from cartridgesave.co.uk. I followed their product recommendations by specifying printer company, product, and model. It turns out cartridges are region-specific, and their site does not recognize this. The site recommended and I bought a cartridge which the printer refuses to use, displaying the message "wrong cartridge". I contacted CartridgeSave customer support; they agreed that their UK product would not work in my US product, but they have a policy forbidding refunds once the product is opened, can do nothing for me.
