With your first Ocado shop, any order placed at a new address or your first order made after 90 days, we pre-authorise your payment for verification and include an additional estimated amount to cover the cost of carrier bags and items priced by weight. This is done as we don’t actually take payment until your friendly Ocado driver has delivered your shop.
This amount is only reserved and never actually deducted from your account, although some card providers will show this reserve on their online statements.
Once the delivery has been made and payment has been taken, pre-authorisation will be released back to your card.
