Has anyone subbed using a Prepaid Visa Giftcard?

I'm curious if anyone has tried to subscribe (successfully or unsuccessfully) with a prepaid Visa giftcard. 
 
Right now, without paypal, that's the only option that I have and I have had problems with some sites in the past using them.

Why don't you just try and then tell us.

1. Because I don't want to waste money on a giftcard in the event that it doesn't work. It's smarter to ask other people if they know.
2. Because I want to sub for a year, but I don't want to pay shipping for the shirt. I'm waiting for see if they will offer the option to decline the shirt.

I used those cards for WoW a few times. You can register the gift card on their site, then it will work as a normal credit card for online transactions.
