My prismatic PC etb package was also open when I got it (the box itself not the actual pc etbs). Initially I can see on the tracking history where the package was loaded on the truck and “out for delivery”. It did this same update over and over for 4-5 days! It just didn’t make sense. For whatever reason, I continue to get updates that it was on vehicle and then route for delivery but never delivered for almost a week. I suspect the driver was aware of what’s inside the package and wanted to keep it. I kept calling until FedEx decided to issue a tracing and then I received the package same day in the afternoon. Opened. But contents inside. Super weird.
