So I told the buyer they had to pay before I shipped. They did, and then sent me the weird following message: "If you already haven't done so, don't forget to upload the tracking number into the eBay system so they know you've sent it. This helps protect you in case something happens to the package enroute. I think if you printed the label from eBay the tracking number is automatically uploaded." I should have known this was weird, but i am just a student trying to sell my books, so I shipped it. Fast forward a week, the item was oddly sent back to my city after being in theirs. No Delivery or anything, just sent back. Now it is in transit to them again, so I decided to google them and yup... SCAMMERS. I am just so upset so I sent them a warning and I contated eBay customer service. He told me he was going to investigate and I sent him a link to this page so he can see they are known scammers. I just hope they actually do something because I warned them that I can already foresee something happening to my book in transit.
