what to sell at a flea market?

I was looking for an out of the box idea about something to sell each week at a flea market. (I wish their was a way to raffle items off). Can I sell a cd of an ebook if the rights to resell came with it? What would interest many people in the current economic condition we are in? Thank you all for your answers.

Sell anything you don’t want. One man’s trash is another man’s treasure.
