How to conduct a part exchange?

i am looking at exchanging a set of wheels with trailsman73…he is in america and i live in ireland.
has anyone had a similiar experience??
what is the safest way for us to both feel secure??
any suggestions are welcome

You each call a bike shop in the other persons city. It’s important you pick the shop so you know it’s real. Then, drop the wheels off at the shop. You then call the shop, confirm they have the wheels, that they are in good shape, then have the shop ship them.

thats a very good idea…much appreciated!
