I have a feeling most vendors have already looked up their products on eBay.
I went to the flea market a couple of hours ago. First time. Didn't buy anything. It was pretty much what I expected - a giant garage sale.
I guess there must be a rule against selling new items. I go to a giant flea market in Denver and many of their vendors sell new stuff like luggage, cell phone cases, and cheap electronics. Almost everything at Expo was used. Except for the confederate flags. You could buy those new in the package.
I was a little turned off when the guy collecting admissions wouldn't allow the people in front of me into the show because their service dog was in training. The admissions guy even pulled out paperwork to show the people he didn't have to let the dog in.
