I placed an order on June 3rd for a Logitech mouse that shows "Get it by Jul 29". I hope to use the new $100 for May-June. The pending charge has been dropped and disappeared from my AMEX account currently. Will the charge be confirmed and show up in my AMEX account in a few days even though Dell does not ship the mouse until July?

If Dell ends up shipping the mouse in July, will the charge show up in my AMEX card as June spending or July spending?
