Sellers at Tesco are third party sellers we have invited to sell on Tesco direct. These are companies we’ve selected to provide you with a wider range of products to choose from in one place. They are a mixture of well-known high street retailers and specialist retailers who operate online. Plus, you earn Clubcard points on all seller orders.
