It's interesting when you look at other recent purchases for the non payers. I've noticed a few have bought a similar item a few bucks cheaper, so they then refuse to pay for the second one. If I can see they have bought a similar one cheaper, I don't even bother with a resend of the invoice, I just got straight for the jugular UPI. 0 feedback buyers I will try the communication route in case they're having trouble with the actual payment. I've talked a few through paying with PayPal and they've all been very grateful.

Glad it all worked out with your buyer.
