well, I can give you 1 example. Lately I have put chips up for sale with a make offer. Why? well, I have a lot of chips that I paid, lets say, 15 to 30 bucks for and of course now, many can be had a lot cheaper on ebay. For instance one chip I bought 5 or 6 years ago for 35.00 shipped and at the time that was the going price for that chip. Now that same chip can be bought on ebay for 5-7 dollars. thus, the make offer...knowing I cant get close to what I paid for the chip so just tiring to get the best price I can for the chip.
