I'm so sorry this didn't work out for you.
Although, if you deal with craigslist often, you'll find flakes of all sizes, not just buyers but sellers. Last month I sold 99% of what I owned, packed two bags, and moved from PA to AZ. I sold or gave away everything using craigslist.
I had two sales fail and they held the item with a deposit. In the end I had to give the items away for free cause it was just too late to relist them.
So while it sucks for you,...
