eBay

I have sold this week two vineyard vines pants which both of them appear on eBay as paid but it does not show up on my Paypal account. I asked one of the buyers to send me the paypal statement and they did, the paypal that was sent to was not mine it...

I bought a jacket on ebay and its been a week and the package is stuck at " Departed USPS Origin Facility " why is this? is it usps tracking? is my package lost? what can i do if its lost ? Thank you
