Autospec,
I recently had someone make a lowball offer (call it 50cts on the dollar), which I rejected within minutes. I then rejected it, only to get the same offer back (same price, same "buyer") within a few minutes. I rejected that one, and got yet another low offer (barely higher), which I did not respond to. Two days and one minute later I got yet another just a tad higher. Sometimes it is not worth my time to simply reject a string of offers which I don't view as serious.
