If you're buying from a seller who offers a warranty, you can find the relevant details on the product page.
Refurbished products should have warranty information listed in their refurbishment notes, which can be found in the 'Refurbished' tab of the 'Compare Sellers' section.
Don't forget! For extra peace of mind, all eligible purchases are covered by OnBuy Protection, which covers you for up to 180 days after purchase, no matter how you paid. If your product arrives faulty, damaged, or different to how it was described, and the seller isn't able to help, you can make a claim.
