We love the vintage skateboards you found. What other unusual things have you come across?
"I've come across some pretty funny items. Some of my favorites were a 1970s vibrating exercise machine and an already assembled, complete Art Deco bar (for a measley $15,000)."

How can you get a good deal on Craigslist? Do you recommend bargaining?
"I absolutely recommend bargaining, but always use your best judgement. Some sellers are open to it, while some are mortally offended. If you're going to bargain, sometimes it helps to give a reason. For example, I recently came across a Restoration Hardware table that was listed for only $100 less than the same brand-new table online. It's not worth the average person's trouble to pay so close to retail value for something used — not to mention something that they have to pick up on their own."
