Amazon needs to make payements more immediate!

The service is good except for the fact that they only bill me like 24 hours after I order something. I need to keep my cards locked, so this late billing thing is not going to fly. Bill me when I unlock my card to pay, not the next day after I assume the payment has been made. Ridiculous! I have to call every time. I just want to import an item. SA is not a safe place and my money gets ****** if I leave my card unlocked for even minutes.
