Amazon ships my sh**t through whatever means they want, but rarely is it with the USPS...is this for slower shipping options or something?
Unless it’s same day/two day it’s almost always shipped with USPS and handed off for local delivery.
Most of my stuff from Amazon ships through USPS but sometimes through UPS. I think Amazon just uses whatever option is cheapest based on where the warehouse is they're shipping from, where it's going to, and when it needs to arrive.
we have Prime so everything comes "2 day" (which sometimes means it's there the next morning, sometimes it means next Tuesday night). We order a lot of dry goods and clothes and gadgets and what not online, Prime saves a ton of money. Plus their streaming service is actually pretty good as a complement to Hulu or Netflix.
