I feel the same. Like ebay though it's a necessary evil for me. Lately I've been getting alot like this via text:

Guy: Do you still have the file cabinet. I'm interested in the Hon one and can pick it up today.
Me (literally less than 5 minutes later): Yes i do. I'm available any time today......
Then NOTHING!!! Never heard from them again. It's actually been happening quite a bit lately
