Since this thread is pretty slow, I'll post another recent thing.
I have an assload of beer in my basement office, including some bottles that I'm not even that excited to drink. This problem is complicated by the fact that I'd be able to sell some of these bottles for decent money if I were so inclined. So I might look at a bottle that sells for $100 and say, "There's no way I'd be willing to pay that much for that bottle; it's not worth it. Therefore, I shouldn't be willing to drink that bottle knowing I could exchange it for that much." But I'm also not interested in selling beer for cash - it seems wrong and in a worst-case scenario I don't like the idea of being identified as a guy who unintentionally sold alcohol to a minor.
To make a long story short, I decided that if:
a) I wasn't going to drink some of these bottles
b) I wasn't going to sell them
I'd try to barter them for something I did want. Garmin recently came out with some new running watches, and I was coveting them. But I already have a functional running watch and couldn't justify the upgrade. So a couple of weeks ago, I posted the following to a local beer trading group on Facebook:
For Trade: Old Stouts
In search of: New Garmin 245 watch (retail $299)
Within 20 minutes I had 3 offers, and the first person to offer was willing to drive up from Kentucky to Ohio to pick them up (which he eventually did). Basically, I think I undervalued my beers by about $100-$150 - I should have aimed for the higher-end watch. But now I've got a nicer watch than I had before, and I have zero regrets about the 2 bottles of beer I no longer have. I'm not sure if I'll do something like this again, but I feel a certain sense of accomplishment for trading something that I didn't care about for something that makes me happy.
[It was pretty interesting on the Facebook thread to see someone say something like, "Hey man, it seems like it would be a lot easier to just sell these for cash, and then you could use that cash to buy whatever the hell you wanted." Obviously that guy was right, but I'm much happier with the barter for my own idiosyncratic reasoning.]
