That offer was real. But no real chance of it being signed. I will give you an example.
Years ago, my wife wanted a very expensive item that I found ugly and useless. It was on Ebay and the starting bid was 900 dollars. I did research on Ebay and saw that this item would not be sold for less than $1200, as that was a used and average condition version of the item. I told her we would put in bids and started by requesting $950. The bids kept going up and asking me to offer more. I played this game until I got to my last offer of $1,150. I told her at that point we need to tap out because the price was getting out of control. She agreed and moved on with her life. In this scenario I bid big money, but I knew my offer had no chance of getting accepted by the seller and it made it appear to my wife that I tried hard to make her happy.
