Once you’ve finished shopping, select online payment. You will be asked to enter your payment card details in the online form. Then, the total amount of the price of your shopping increased by 15% will be blocked on your card. However, your card will be charged only after your shopping has been delivered. As a rule, financial institutions charge an account using the amount that has already been blocked, so because of this process, the blocked amount will be freed. It is possible, however, that the financial institution does not charge your account using the blocked amount, in which case the blocked amount will stay there. Given that Tesco has no control over the process of such financial transactions, Tesco excludes its liability for any damage they may have caused.
