Yeah, prices have gotten quite high for some things.
With the increased interest in retro/vintage computers it is not all that surprising.
I bet some of it has to do with the reduced availability because there are those of us who have a horde of parts that we need to go through and sell most of them.
I have had people come back with a counter-offer that is only a tiny bit less than what the original asking price was.... seems silly to me.
When I am selling I usually enable the best offer option as well. But I also don't generally list an item for a whole lot more than the minimum I would accept for it either. So if I am selling something for say $50, don't expect me to accept $40 for it, especially when I am offering free domestic shipping. I know what I am selling and what I should reasonably be able to get for it.
What is interesting is that a lot of time when I watch items, I will get offers from the seller for anywhere from about 10% off to 25% off. Guess they are hoping somebody will buy it at the asking price.
The last card I bought recently, the original asking price was $150 or higher.... I had been watching it for I think around a month and then it was lowered to $90. Then I got an offer form the seller for another $20 off so I took it. Shipping was from overseas so the shipping was of course kind of high. Figured since it was pretty much a one of a kind card (no pictures or other information I could find online) I would buy it.. now just waiting for it to get here.
So my rant is.... why am I so attracted to insanely rare cards? I'm not even sure I will use it besides testing it out.... bleh.
