I'm looking for tickets to the My Chem show in May.  I have found some at some decent prices, but I'm reluctant to buy 'em at this point.  There are different tickets for sale for General Admission and Floor.
I know 9:30 is a GA venue, which makes me question why there are different types of tickets being sold for this show; I feel the need to question their validity.  
Maybe it's a dumb question, but I don't do shows.
So any advice would be cool.
Thanks.
