I buy and sell a good amount on eBay and I have noticed that USPS has been really bad with certain packages. Look at this package. It was shipped on 5/26 and the last update is 6/1. I live in Maryland and you can see it was in Maryland on 5/27 and then went to Chicago. 🤦♂️

I have one friend in Thailand who ordered masks from the US and it was shipped via USPS. It left back in March and he just received it last week.
I have had one buyer offer me $30 to ship the item FedEx instead of USPS 😂
