Just to add to the rest of the comments here... I did try to follow through with the order, and used a credit card number that is used for testing, and that at least 2 online shopping carts that I've used for sites give out to the people installing them as non-existant numbers to test that the system's working. First time I got a "amount can't be 0.00, try again" message. Second time I got a "duplicate authorization". Considering that the site doesn't seem to be secure, I'll have to pass on this too. I don't want to sound ungrateful, but why can't you just set it as a download? It's more cumbersome to do things this way.
