I mean you get scammed maybe twice by a company, then buy somewhere else. You quickly realize that it is better spending 3-4 times the amount of money for something that will last 10 years than buying stuff that do not work or keep breaking after a few months/years.
I am too poor to be able to afford buying cheap stuff.
Most people still just buy the cheapest version of an item they are looking for.
Also, I am not trying to hyper optimize my use of time, but rather I find the experience of huge selection, fake reviews mixed with sponsored listings to be very unpleasant. I have slightly more faith in quality control at a department store, or even a dedicated housewares store.
One of the depots used by DHL when they "can't find" my building (even though the place predates the formation of the Soviet Union, let alone its collapse) is about a mile away and I don't have a car. This is fine unless it rains, but it's not even conveniently on my way to anything interesting.
I bought a VOIP phone from the media store recently. When I was there looking at them, and feeling them etc, I was thinking how there is no way I could have picked the right one from an online shop. I might have never known there was something better, I guess. But being able to hold them helped me pick one I thought I would like.
