Why are mopar parts so scarce at swap meets?

I too only go to Mopar only swap meets, but I do very well selling at them! I traditionally like to take larger items to swap meets to avoid shipping them! I also hardly ever sell anything early A body related at the swap meets I set up at, and instead make way more money on 67 and up A stuff, and B body parts! I make most of my early A body sales right here on FABO, where there is a large concentration of early A enthusiasts! I agree with Ramenth on this one, the Internet has changed the parts selling game, I can now sit back and list a few items on Sunday afternoon from the comfort of my garage, not some cold, dank, Chevy infested barn sale!!!
