I sell around 50 items a month on ebay and have seen most of the dirty tricks people play to either get out of paying or try to get money knocked off for supposed damage since ebay took away sellers powers in leaving buyer bad feedback this number has gone up big time,I now send everything recorded or by courier which has made all my prices go up reducing my amount of sales but it gets me the all important tracking number which paypal and ebay always want or they simply give in to the buyer every time.
