Seller requested a BIN price be listed so they could buy an item before auction ended. Buyer paid listed price and immediately requested that the item get shipped that day without requesting expedited services. Tracking number was provided same day, package was mailed out the following day (listing had a 5 business day handling time). Buyer messaged me at least 20 times demanding that I ship the package faster, telling me I was a scammer. Seller opened a dispute before even receiving the product and after shipping receipt scan was provided. Thankfully ebay ruled in my favor, since I followed all the steps correctly, but it was no fun having $600 on hold for 2 weeks.
