They use UPS. I told myself I would never use anything except FEDEX, but I didn't listen to myself. This definitely wasn't the same UPS man who comes during the week. I'm guessing this was their weekend guy. I know that our FEDEX has a man during the week and a lady on weekends. The meds are the same as what everyone else orders hydro 10/325. Nothing was any different. I'm racking my brain trying to think what was different. On the VIP board someone mentioned that this happened twice to her, but it was FEDEX and not UPS. She said that the FEDEX guy came in his own car and was dressed in regular clothes. As a matter of fact this is what she said: ""Yep! It's happened twice now, except it was FedEx. VERY strange, he told me FedEx contracted him because they were overwhelmed that day. The package was trackable on the FedEx website and he had a standard FedEx clipboard with dozens of signatures, but it still freaked me out. Has anyone else have this odd experience?"" My package was trackable too and he had a standard UPS clipboard (but I didn't notice if there were other signatures on it).
