Samsung will not charge you until your order has been shipped. When you place your order, a hold for the funds will be put on your card for the total amount, plus all taxes, fees, and shipping charges, if any. After the order becomes ready to ship, the payment will be authorized to be made and the charge will occur.
When happens when the authorization period ends?
Samsung will release the funds to your financial institution to approve the authorization. The actual time that it may take for the the funds to be released depends on your financial institution. It may take up to 7 days for full release.
Note: Orders placed with PayPal are charged immediately after the order is placed.
