My question is, similar to Benjamin_gates, if you sold him 15 CDs, when you go to the post office with the package you would have to send it priority, I recently sold about 13 CDs when when it took it to the post office it cost about $18 to ship it and when I asked how much it cost to ship the item priority they said that was priority because at that weight it could only be shipped priority. So it seems like he asked you where the package was and you claimed you had shipped it first class to explain why it was taking so long for it to get to him but he caught on to this and cancelled the order because he knew it had to shipped priority so he thought you were trying to rip him off since you were lying to him about the shipping.
