On the 24th, I simply went to the UTD website, clicked the link, it asked me to log in with my user id. I did. And it had the info from my recent mini purchase(recent being It was just shipped on the 24). I didnt have to input the serial number or anything from the mini. It asked for the credit card info, and away it went. It charged the card yesterday.
Tonight, I went back to the same UTD website, clicked the link, logged in, this time I had to go through the enter your serial number, which I had recieved the mini last night, and so I input it in, along with credit card info and away it went creating a different order. No charge has been charged yet, but its early for the second one...
