We have a Cashback program.
This means that with every purchase you receive 10% of the total amount (excluding VAT) in the form of Cashback.
This is tracked in 'Your account'. Look at 'Transactions' to see how much you have already received.
During checkout you can use this to pay.
It is important that you go to the 'Shopping cart' and not directly to checkout.
At the shopping cart, if you have a balance, you will see a screen in which you can indicate how much cashback you want to use.
