A low ball offer, on a popular item, which has been listed less than 24 hours. I like it when they add a sob story about how much they want it but this is the most they can do. You'll never know unless you ask, I suppose.
If I had a little gumption I would sell more stuff by auction, because the corollary to the absurd lowball is that once they've made a bid, people will often pay much more than necessary to win an auction. But, back in the early oughts I auctioned a Pink Floyd concert bootleg LP and the winning bid was $1.25, so I've been wary of selling by auction ever since.
