Upper Deck has a section on their website for this, so you don't have to send in any envelopes. I have done it a few times, but never got anything. I have been tempted to do it for some of the higher end sets. I wonder if they have something like this for Topps Dynasty...now that would be incredible to get one of those for the cost of a stamp.
