@Tinkeringbell I find that the delivery services (USPS, UPS, Fedex here) are usually pretty reliable, although tracking occasionally shows interesting paths with my package going back and forth between two cities on the route. But smaller companies and independent contractors show up almost at random. I gave up on the company that delivered my oil and maintained my furnace after the THIRD time in a row they simply didn't show up.

@Tinkeringbell And only way I found out was to call them at the end of the service window and the office said something like "oh yeah, looks like they aren't going to get to you".

Even the shops that have their own delivery services are usually great here when it comes to tracking and delivery time frames
