The quality and utility of Craigslist varies widely by location.
We bought my dream desk from Staples in Utah before we moved. We actually hoped to set it up in our old house; it was part of the plan to reconcile ourselves to living there forever. But then we got word that we'd be moving out here and we decided to just hang on to it. Easier to move in its original packing, you know?
Then we arrive here and the desk dwarfs our little condo. So without even opening it, we decide to sell it on Craigslist. It sells for $450 new from Staples, so we decide to list the desk at $350.
In Utah, the desk would never have sold for that price. April and I wouldn't have paid that price for it new, anyway. We got it on sale for $300!
Here in Northern Virginia, within 12 hours of posting it, it was sold and gone.
We also got three of the exact model of Ikea stools we were looking for from somebody else on Craigslist for less than the price of one, new.
Conclusion: We're not in Kansas anymore. And while that has its downsides, it has a lot of unexpected upsides, too.
