Paying for Your Order
You may pay for your orders with Best Buy gift cards, a Pitch In™ Card, our electronic digital coupons, PayPal, and with a Best Buy credit card or major credit cards issued in the United States of America. Currently, we accept Visa®, MasterCard®, American Express® and Discover® Card.
Generally, credit and debit card are not charged until we either ship the item(s) to you or confirm store availability (at which time you will be charged only for the goods we have actually shipped along with any appropriate taxes or shipping charges). However, we may pre-authorize your order amount with your credit or debit card issuer at the time you place the order, which may have an effect on your available credit line. When paying for a preorder with a debit card you will be charged at the time you place your preorder. Please contact your credit card issuer for more information.
If you ordered a special delivery item, you will be charged once a delivery time is confirmed. For digitally delivered orders, your credit or debit card will be charged at the time that you initiate the download of the product.
Ah, so if I use my debit card I'm charged in full when I place the order even though its a preorder. I don't use credit cards.
