I thought maybe I can ask this here as Bar Sport is a place for anything. Serious question but nothing to do with Arduino or electronics.
I've just had some boards made by OSH Park in the US. I've just had the notification that they are being shipped. I chose USPS as the cheap option and I know it will take 3 to 4 weeks to get to the UK. What seems odd is the tracking link they gave me is to UPS, which, as far as I know is United Parcel Service or something like that. I use UPS in the UK and they are good. I didn't think UPS was the USPS, or maybe it is? Are they related? Are they the same? Or have OSH Park sent my boards by UPS when I only ordered USPS? Or something else?
