I paid for a product and I should have realised when asked me to wait for 25 days as they were having problems with the post.  It just took me out of the 30 days timeslot to get a refund.  They never intended to send the product and its just a scam

Scammers target sellers with less than 10 feedbacks, who are selling very expensive electronic items.  They are relying on the sellers inexperience in order to scam them.  So my advice is to build up some experience and feedback by  both buying and selling before you list expensive items.
