When an order is placed and the payment method is credit or debit card we initially take a pre-authorisation against the card for the full amount of your order. This authorisation ensures the funds for the order are available. “Double” or “Pending” charges may appear on your bank account if one or more of the items are on backorder as we are unable to use the original authorisation twice. Once your order has despatched, your payment will then be charged for these items.
The exact time frame for removal of the pre- authorisation is determined by your card's issuing bank.
