This is the way it worked for me:

Email inviting me to order, with the url to order with. I ordered as soon as I read it :)

Confirmation of Order email, repeating my order and address so I could change it if there was an error. It also included an estimate for what date they would ship the empeg out.

Confirmation of Shipping email, stating that the empeg had been dispatched, which carrier had been used, and the tracking number so you can track it's passage on the carrier's web site.

Right now I'm hitting TNTs web site every hour or so..

If you wait, you'll be emailed all the information you need :)
