I think what you're talking about is the preorder non-refundable charge. That will be charged after you place the order. The rest will be charged once the item ships, or if you use flex pay the rest is charged in monthly payments the 3 months prior to shipping it.
After that, they send you a defective item....(couldn't resist)
No scaring new people! If you ordered an in stock item it will be on its way to you in 24 hours. If you ordered a pre-order item with a non refundable deposit, then the NRD will be charged and then the item will be charged to your card when it comes into inventory. Please keep the order page bookmarked as the estimated shipping times will be updated there.
If you ordered flex pay then your card will be charged based on the schedule you agreed to and then the item will be shipped shortly after the last payment.
