Like time capsules, secondhand stores can shed light on what was popular in the past, such as books about installing Windows 95 and a DVD filled with tutorials explaining how to install Windows 95. Turn back a page in the book of fads with today's Groupon: for $15, you get $35 worth of books, CDs, DVDs, vinyl, and more from Second Edition Books and Music in Columbia.

Since 2005, friendly book monarchs John and Kathy Byer have built a browser's kingdom of more than 15,000 books, recently adding legions of DVDs, CDs, and vinyl to their burgeoning empire. Each hardcover and paperback comes neatly arranged by type, from romance to children's books to science fiction, and they range from 50%–80% off the suggested retail price. Nostalgic VJs and cash-strapped Frisbee dogs will happily sniff through the DVD selection ($4 per disc), the sisterly compact discs ($4.95), and their great-uncle vinyl ($3.99). New trades occur weekly, rendering Second Edition a valuable hub for anyone looking to pan for gently used gold, dog-eared Newbery Medals, or gently-eared dog gold.

Reviews

Three Yahoo! Locals give Second Edition an average of 4.5 stars, and five Yelpers give it four:

• …Second Edition is worth your time and money to explore for books that you've always wanted to read but weren't willing to pay the full price. Plus, there are movies and CD's you can buy. Friendly staff too. – Larry G., Yelp
• Don't be fooled by its average strip mall appearance, it's really quite a gem. . – Ralph G., Yelp
