How long after placing an order before it is processed?

[starsis1]

First of all, happy Thanksgiving to everyone.
I have placed an order for the digital download of a couple of games earlier today using my credit card and got a message saying that my order is being processed and that I would be getting an e-mail once it is completed. Is there any manual processing involved in handling orders? Should I expect to be able to download my purchases today?
Thank you

How did you pay?

When I buy DD, I pay by credit card or paypal, but each time, I am presented with a webpage with an HTTP blue button link showing the Dowload Now" or some such message. I've never had to wait for an order to be processed...ever.

After several hours I got an e-mail confirming my order and was able to download m purchase. Thx
