Buyer purchased a $2.00 red seal note for $5.24 with free shipping. I shipped it in first class letter. He waited until I gave him feedback ( just under 30 days) to claim he didn't get it. Since it was a small value item, I didn't track it. Just sent it first class, very well sealed and with little to attract attention. Its my own fault to not track it but if he's lying its still fraud and maybe my report can help catch him.
