It used to be that when you ordered something with free shipping, they shipped it fairly quickly, so how long it took you to get it mostly depended on the speed of the carrier. I would often get free shipped items in one or two days if they came from the Amazon warehouse in my city.

Then they changed that. If I ordered something with free shipping that was going to ship from the warehouse in my city, they would wait several days before shipping it, and then the carrier would deliver it in one or two days, just ensuring that the item would not arrive earlier than the advertised arrival window.
