I have traded several times to finalize a deal. I have left money on the table both times just so we could acquire the title that was desired.
I have also set up deals where the seller would drop off a machine at my house. Of coarse, cash was paid on my end & this was agreed upon several weeks in advance. I live four miles north of the York Show, so this is a win-win for everyone. The seller walks away w/ cash in hand, machine free & a wad of hundreds to spend at the show.
