Want to buy something I seen on the show how do I go about that

Give them a call and good luck because they don't seem real interested in actually offering things for sale that were shown on the program except a very few of the most well known pieces, and even then they are priced to reflect their value due to their effectiveness at drawing tourists to their stores rather than to be sold at a fair price. I say this because their stores are mainly t-shirts and other souvenirs rather than large buildings full of cool antiques. They definitely are designed more to promote the show than their antique business. Especially the store in Nashville which is tiny.

Contact them by phone or e mail, or visit the store if your in the area.;but to be honest with you it seemed like the store is more of a front, or museum to the show than an actual store. "Plenty of t-shirt's,hats,mugs,etc."so good luck!

T Mel beat me to the answer and said it best. The building holds lots of other smaller shops with cool finds also, so it's worth exploring if you're not looking for something specific.
