QUICK❗️ Canceling Amazon order.

Say I placed an order on Amazon and then cancel it like an hour later and then place the order again (I want to change the address. Not a big deal if I don't though). Will my card be charged twice and then have to wait for the refund of the first one? Or will canceling it automatically put that money as Amazon credit that will then be used to order it again? Or how does this work? Anyone know?
