RE: What would you do?
I sold a plane and advertised the shipping and handling would be $20. I took the plane to the post office and found out it cost $47 to ship it!
I had to eat the extra $27 since the deal was already done and he had sent me the money for the plane.
I'd tell the guy either send you the plane or you want your money back!
HE's the one that should learn by his mistakes...Not You!
