I would wait till you get your money back from Paypal before leaving any feedback.
You
might get your item from him sent late, so I'd leave it a bit longer.

This isn't the first time something like this has happened with this particular seller - I believe he had health problems and had to spend time in hospital when this happened before. It might be that he has ongoing health issues, I've no idea and I haven't heard anything about him through the grapevine either ... I'm just saying y'know ...
I can remember his wife had her hands completely full contacting people last time around on his behalf over items being delayed ... anyone heard if Jon's okay or not?
