Planet Comicon Preperations

For the second year in a row I went to Comicon here in Kansas City. It was a fantastic time. I met a bunch of indie authors, illustrators and will hopefully make some good connections with them as time goes on, but this isn't why I am writing this post.

Next year I plan to rent a table and sell some paperbacks. I would have this year, but the idea of getting a table didn't occur to me until it was too late to prep properly for the convention. To be honest, I simply didn't think I'd be able to go at all. My stories are more in line with a comic series, but since I can't draw much more than a happy face, they are in a novel format.

It's a 3 day event and here's what I'm thinking of taking so far.

For Sale:
30 copies of book 1 (maybe more)
10 copies of book 2 and 3 (each, I suspect not that many people will buy the trilogy at once, if at all)
30 copies of Hitori (its a standalone, should sell as well as book 1)
Based on my usual writing speed, books 4 and 5 should also be out. I will not be bringing them.
Of course, I will sign my name on whatever I'm asked to  :P

Free Swag:
Bizz cards (via Vistaprint)
Bookmarks (same deal)
stickers?

Decorations:
Large banner to go across the front of  the table (cover of first book)

So here's the point of this blog entry: I'm looking for more ideas. As a person going to a comicon, or really any convention, what do you like to see in terms of freebies and purchasable items. I had the idea of getting some t-shirts made up, but I truely wonder if it's worth it. I'm a pretty unknown author (that's slowly changing, thanks!) so I doubt anyone would buy a shirt unless it was completely silly. Any ideas or thoughts?
