Julia Wilkinson has been selling on eBay since 1999, listing everything from software to clothing to a stove (local pickup only on that last one). She is the author of "The eBay Price Guide" (No Starch Press, 2006); "eBay Top 100 Simplified Tips & Tricks" (Wiley, 2004-6); and numerous ebooks, including "What $ells on eBay for What," http://www.yardsalers.net/bookstore.asp.

Her newsletter, Yard Salers, at www.yardsalers.net, discusses finding great stuff at yard sales, estate sales, and thrift shops, and most importantly, having fun. She also writes a blog, "bidbits," at http://juliawww.typepad.com/bidbits.

Julia writes occasionally for AuctionBytes.com and has been pleased to cover eBay Live for AB since 2003. Her writing has also appeared in Reader's Digest, The Washington Post magazine, and other publications. She attended the University of Virginia, and lives in Virginia with her two kids, husband, and a cat who has inordinate jumping abilities. She's not too proud to patronize gumball machines.
