If you're not home for extended periods, it'll be tough to manage auctions unless you schedule them to occur only while you're not away. Otherwise you'll be scrambling to get items shipped as soon as you return. Not a fun way to come back from a road trip.

And with ebay, you can pretty much count on some transactions being challenged, no matter what you do. This is part of what makes online selling there so crazy. It's the biggest market, but also the one with the most risks, and often they crop up just when you don't expect them.

You're in MPLS, which is a huge biking community. There's a big swap that used to be held in Blaine right about now, and a few others as spring nears. If you wanted to clear out a bunch of stuff at once, a local swap is one way. Don't get as much $, but you won't have to worry about stuff being rejected on the back end like ebay, and there's no $600 limit to what you can make in cash.
