A couple of years before we moved from Alabama in 2007, we accidentally stumbled upon McKay’s Bookstore in Chattanooga, Tennessee. I’d never seen a bookstore the size of a college library with every book genre available. They also sell/trade CDs, DVDs, games, etc. We were in awe!
McKay’s also has a trade-in or you can sell your used books to them. We had boxes of books in our house and not enough shelves to set them on, so we took them to trade. You can either get cash for the books or a voucher for the same amount to ‘buy’ books from them. This was a good deal. We were able to trade for dozens of books we had never read but still didn’t have enough shelves for the ones we brought back.
They had a lot of used D&D books, fantasy art books, and sci-fi art books. I don’t play D&D, but I find some of the art inspirational for possible creatures in my novels. In the 2000s, these books were fairly priced, and I was able to buy some harder to find classic books.
Back then, we traveled often between Alabama and Kentucky to visit family. During one trip, we noticed another McKay’s bookstore in Knoxville, Tennessee. We had to stop, only to find this store was even larger than the one in Chattanooga.
I’ll be honest. If you love books, you can lose track of time in both of these giant bookstores. If you collect comics, they now have a much larger selection of comics. Not rare ones to browse through, but behind the sales counter and in glass-enclosed shelves, they have some rarer comics and a lot of collectible statues and busts of superheroes.
This past weekend, being strapped for time, we forced ourselves to comb the shelves far faster than we would normally do. I looked forward to seeing what gaming books they had, but was sorely disappointed with their prices. Not that I think they should underprice themselves, but when I can get the same book in NEW condition on Ebay, Walmart, or Amazon, a used book shouldn’t be the same price or higher 
than a new one. Some of their trade paperbacks were priced at a high price.
One thing that impressed me at both bookstores was there are no shortages of people who want and are seeking to have physical books. People were buying them by the basket-loads. So book-lovers, if you’re ever in Chattanooga, Knoxville, or Nashville (They have other locations, too), plan to take the time to stop and check them out. If you have a stack of books you wish to part with, trade them in.
