In a few short days, I'm going to: St. Louis Comic Con - http://stlouiscomiccon.com/

Where I have a table rented out to sell books and I'm not sure exactly what I'm doing.

Does anyone out there have any tips for how to sell things better at a con? I just planned to have all the books out on display and to have a tablet playing a video displaying the prices... plus the display copies will have prices too.

Any tips for running one's own table at a convention would be much appreciated :3
