No comfy couches or cappuccinos, but lots of great bargains at one of Atlanta's last independent booksellers.. In Short Markdown prices make this Atlanta bookstore chain a perennial favorite. Bestsellers are always 30-percent off, and Oprah's picks are reliably stocked, too. The store's inventory is discounted somewhere between 11- and 75-percent off the cover price. Decor consists of walls painted "Have a Nice Day" yellow, and there isn't much room to sit down and read. This no-frills approach pays off at the cash register--faster than you can say Clark Howard.
