If you live somewhere where the 2 day shipping actually gets to you in 2 days, you live close enough to a brick and mortar store where you can get whatever you need even faster.

I'm always looking for ways to avoid Amazon, and if I had a car, this might be true, but because I live in the downtown core where parking is extremely expensive and transit covers most of my needs, I don't have a car, although a significant portion of the retail stores near me have shut down in the past few years. So, if I want to buy things from a brick and mortar store that's not a grocery store or random boutique, I have to spend 45+ minutes each way on a bus to the stores in the suburbs. And since I'm on public transit, picking up bulky items, heavy items, or a large quantity of items is not very practical. A large selection of Amazon's items are available to me via same day or next day shipping (and they show up on time ~97% of the time), so they actually do get to me faster than figuring out how to get the same items from a brick and mortar store. I have most definitely wasted 2 days running around to various stores only to return empty handed, and eventually order it from Amazon anyway.
