While I was at one of Florida's Largest Flea Markets I picked up one of their Magazines for vendors... "Swap Meet" is the name of it and inside it has a TON of whole sale sources...
http://www.wholesalesources.com/ is the main link which has a TON of lists for other wholesalers.
"Swap Meet" is part of the National Fleamarket Association and my dad has purchased from a few of their wholesalers that were advertised and recieved good product.
I know I sound like a complete advertisement right now ROFL But I knew that some of y'all were interested in this type of thing :) I am in no way affiliated with any of these merchants... just saw the mag and thought I'd tell y'all about it :)
