The problem with this is that not linking it means that you are forcing people who *don't* want to see it to have to look at it. If you don't care enough to click a link to look at the information... clearly you don't really care.
Now 50 lines would be a bit much, but I can live with 16.
Most posts are smaller than 16 lines (often MUCH smaller). Really, really long signatures make threads require a lot more scrolling than they otherwise would. Personally, I think they should limit it to no more than 4-5 lines, but they haven't.
Anyhow, WRT buy.com: the only real 'problem' I've had with them is that I bought an item with a rebate -- and it turns out they were advertising the rebate before it was valid! My rebate got rejected because I bought the item before the rebate officially started, yet they were already advertising the reduced price. Fool me once, shame on you... fool me twice, shame on me. I'll definitely look at any offers from there MUCH more carefully from now on.
Cancelling your order is pretty lame -- but I doubt there is much you can do directly, as long as they refunded your money. Their terms and conditions, while scummy, are clear, and almost ANY store has a 'we can cancel your order at any time for any reason and refund your money' clause of some sort. If you press the issue legally, they might just turn around and claim it was a pricing mistake or something like that, and good luck proving otherwise.
However, you should: complain to them, complain to the BBB and your state AG, write them up on resellerratings, tell people not to shop there, and tell THEM (see if you can get a name/address and send someone an actual letter via certified mail rather than an email) that you're telling people not to shop there because of your experience.
