What's up with the ridiculous offers?!?

Is it just me or are the high volume of low-ball offers surprising anyone else?

Example: I list an item at 60% off what a current, desirable  component sold for new, and I get an offer for half (or less) of what I am asking! I've have been buying and selling high end audio & video gear for over 40 years and I know the value of gear, but I have never experienced such an destructive trend. I expect it from Craigslst or at a garage sale, but not from Audiogon.

I understand an occasional low offer, and it's usually accompanied with an explanation or apology for the balz it takes to make such an offer, but I am getting absolutely offensive offers for more than 75% of what I list.  

Are there any other sellers that would like to commiserate with me? Am I missing something? Is it just me?
