I want to sell a ring worth more than 10 000 euros. There is a one guy in France who is interested. I told him I am not in France yet, but will be there probably the next month. He said he is about to make a proposal to his girlfriend, so he wants it in the next few days.
I would accept to come, but I want to be sure he wouldn't cancel it.
How to tell him to pay in advance at least for the urgent travel into his country ?
The route would cost for about 400-500eu.
