Macmall problem

Hi everyone,

So I just ordered a wacom cintiq 13HD refurbished from macmall.

My only concern is, I clicked the place order button, and it said "please wait. Processing order"
It then left me on the same screen. I clicked place order again, and it said the same thing. I called them just now, and they said it takes a while to process because they have so many orders. Plus they said their website has been down.

1. Did I just got doubled charged by clicking the place order button twice?
2. Is this even a safe website?

I'm super concerned. They said I should have the order number sometime today.

Thanks,
Rockwell
