Reading this thread there are 2 people upset
One the buyer and One the seller...
Number one rule to selling and buying on the internet is stay in contact with each other on the situation re: funds on the way...funds received... merchandise status... merchandised shipped and merchandise received by the buyer...
Avoidance is tabu in sales...
I buy and sell on Ebay and find this formula works well !
I have also set an amount i am willing to spend and loose if that actually happens thought it has not happened over the years..
Just be honest and forth right and treat people with the same respect you wish to be treated too and you will find that people are understanding...
