What is the temporary pre-order authorization hold on my card?

A temporary pre-authorization hold for the cost of your item(s), rounded to the nearest dollar, will be placed on your account until the transaction is completed on your selected pickup date to ensure payment is available in your account upon pick up. The pre-authorization will be renewed by your bank every seven days. If an authorization hold cannot be renewed, your order will be systematically canceled. The temporary hold on your card will be released on your pickup date and you will only be charged for the cost of your pre-order at the end of that day.
