Average price on 340 block

Ive been trying to sell my 340 block .040 over on craigslist for a while now @ $275. All I get are jokers wasting my time. Guys calling me telling me they want it, but then they are a no show. Has happened a few times. I haven't met a decent person on Craigslist yet for anything I've sold. Right now I see it becoming a coffee table in the future.

Wow, that's a good price.
