Once you've paid for your purchase, there are two possibilities: you've paid by credit card and the payment has been validated directly. Or you may have chosen PayPal or bank transfer, in which case verification may take a little longer.
Indeed, PayPal may decide to carry out a number of checks before validating the payment.
In the case of a bank transfer, it's up to the customer to do this once we've sent them our bank details by e-mail.
