I sold a frame to a guy in Poland with no problems.
I sent him loads, I mean loads of pics of every part of the frame every scratch dent, the good bits and the bad. I got him to agree in writing that he knew exactly what he was getting and was happy with the condition of it.
Sent it tracked via DHL can’t remember exact cost £30-40 maybe. Took about a week to get to him. He emailed me day after he recieved it saying he was delighted with it.
Someone on here is from Poland and gave me advice that the address I was sending to was ” an upmarket area”
I Googled the buyers name, he had a FB page and I could see he seemed to deal in s/hand bikes and frames.
Not all transactions are a scam, go with your instinct how well the guy communicates with you. Don’t be scared of walking away tho.
