We get a lot of stuff delivered by post, and for us it is often quicker to get stuff delivered by them than couriers. Being out in the country we have limited couriers, and one of the local guys gets your package he says he doesn't have time to go to your house and will hang on to a package for a few days until he gets around to it.
Our local PO knows everyone by name- you could put our name on with just Moyhu 3732, and mail will get here! Packages get left on the doorstep. Signed a form and they can sign for our stuff and deliver it. Only had a parcel contents from Adelaide go missing once, and that was because the idiot who posted it didn't seal the ends of cylinder and the UHF aerial fell out- only to be found in Melbourne, luckily as I had received the instructions and were able to give them a detailed description of the item!!
