The last time I went to either of these shows was a couple a years ago and there were a lot of vendors either handing out freebies, giving samples or had some kind of raffle/spin the wheel going on to win their stuff. I used to get the free tickets and sell them on eBay, but I think that's a bit challenge now considering they print your name on the ticket. Believe it or not, some resorts actually verify.
As far as the stores that are there to sell product such as Sports Authority and Mel Cottons, I would say there's not much of a deal you can get there, but then again that's all dependent on what you're looking for. If you're looking for the latest Burton Custom or some high end goggles, you probably won't find it there. From my past experiences, it's last seasons items that vendors are trying to get rid of and that's not a bad thing.
