After a too many non payments..I solved the problem my only accepting immediate payments via Paypal of course.
Yes..you can leave bad comments and the FVF back..big woop..to much time has been wasted and more will be.
I have not lost any business or interest from only accepting immediate payment required.
I only sell things that I know will sell and most people that do pay..pay with Paypal anyway.
It's all been good now. I hold all the control since they have to pay first. I was getting so pissed at people buying it now and not paying..

I am not a patient person as it is..
A couple of times I had sold tickets and then the people never paid..money was gone. Never again. Those type of things were mostly newbies.
Anyway..I love the immediate payment required with Paypal. That's the best thing ebay ever did.
I would state 'postal money orders' only and people would send any they wanted and banks can be dicks even though they should take them.
Postal Money orders rock..any post office has to cash them if made out to you.
Never accepted personal checks..ever..to much hassle.
