As everyone has said, be polite and respectful...but always keep one foot pointed toward the next table to make an easy getaway.
You'll generally run into two basic types of sellers: the somewhat flexible guy who you can work with on price a bit
(or maybe a lot?), and the
SHARK who's there to
Always
Be
Closing. His prices
(if he even has price stickers on the cards you're looking at) will be in the stratosphere to begin with and there's no room for negotiation. Even if he were to move down in price a lot, it would still be 200% higher than anywhere else. Flee him.
If a card you're looking for is available at a nice price, buy it. You can attempt to get the seller to come down a bit, but if it's already in the right neighborhood, don't pass it up, because the next collector who sees it
WILL buy it. Regret sucks!
Oh, have fun!!
