Why sealed bids?
Why do I offer items for “sealed bid” rather than at a fixed price? Simple, I REALLY want to sell them!
There is an old saying: “Something is worth what someone is willing to pay for it.” This is very true, however that knowledge resides solely with the buyer, not the seller.
Here is an example: I had a very nice condition, high quality spinet piano for sale. Research showed that it ought to be worth about $1,500. Since I needed to sell it, I probably would have offered it at fixed price for around $500. Instead, I offered it for “sealed bid”. I had over a dozen offers, none of them anywhere near $500. I sold it (which is what I wanted) for the best offer, and the buyer got it for their price (which is what they wanted) and was thrilled! If I had offered it at a set price of $500, neither of us would have gotten what we wanted.
