I'll be traveling to an event out of state and will have some instruments displayed for sale, and am wondering about best practices for handling sales under these circumstances. This will be the first time for me offering instruments for sale as a maker rather than through a shop. I've heard of issues of difficulty recovering property across some state's borders when someone doesn't pay. I'm also concerned about how best to deal with money without getting swindled with a bad check or something. I'm just more concerned overall about working with strangers out of state as opposed to dealing with locals.
Any suggestions on best practices on the financial end of the transaction?
