Typically you can't reserve popular in demand products like newly released iPhones and iPads. They are sold on a first come first serve basis.
You also cannot reserve them on the Apple site for in store pick up either. I think this is possible in the US by paying in full online and then picking up at a local Apple store but not here in the UK.

They don't.

I suspect they didn't actually debit it but just reserved it for debit later at dispatch. Very few online retailers take money at time of order and Apple isn't one of them.
Nope it showed up right away, the money was gone. I even checked my statement over the phone, the money came out
