There have been many items I've looked at or bought, mostly from small-ish manufacturers, that are only available through amazon due to the manufacturer not have the resources to handle all the logistics and web store that come with selling through amazon. I do everything I can to avoid buying from them because I can't stand their bull shit.

If you live remote, say, an hour or more from real shopping and such it’s the way to get fast delivery on anything, though Walmart does ok with this, though their “fast” is fairly unreliable. (Great for front door delivery of kitty litter, dog food, etc)

But no, most people don’t need it because most people don’t live remote.

The fast shipping. Need something the next day? -> Amazon. No other online store can match how fast they are in my area.
