Hello everyone, I'm not new to eBay by any means, But im new to selling. I've had problems when i was a buyer with shipping, But always got the item. I now sold a Galaxy S8 MidFrame with the motherboard and etc with everything but the screen and back glass for 500. I got a respond no less than 5 mins later saying that there was a biD on the item. So i accepted and the seller asked me to send an invoice using PayPal, (which i did) and now im kinda nervous that this was a scam as the buyer marked it as payment sent, But i checked PayPal and i have no payment pending, only the request i sent for 500$. Any help?
