LOL! I had a Russian Motorcycle with Sidecar for sale..The price was 4500.00 OBO. That means, I am sure you all know, "Or best offer" People would make an offer, I would tell them to write it down, give me a 100.00 deposit and I would let them know by X date if theirs was the "Best offer"...They just didn't get it! How do you know if you have the best offer if you take the first offer? Some of them got pretty upset...I sold it for the asking price, eventually...Fun! And then when we were in the horse business.....
