I've never been to a BotCon convention but am considering going to the one this year. That said, I really have no idea how these things work and have a couple of quick questions: 1. Are there different convention packages or memberships that you have to buy to attend? And are they different depending on the price you pay? 2. This is the most important one since it's my main motivation in going: are there sales booths to actually buy TF's from, or only displays to see what will eventually hit the stores? Thanka!
