The first couple of hours of the swap things tend to be pretty chaotic as there will be a lot of people there. This year's venue will afford more space so it shouldn't be cramped. Corals will be available from both members and retail type vendors. Just about anything you can frag will usually be there. Frags typically range from $10-$50 depending on rarity. Suffice to say, there will be plenty of bargins without a doubt so you definitely want to come with some $.
Although there will be plenty more, you can check out fragswapper.com for a preview of the types of things that people are selling.
