Except (?) that it's not like you can do more than look at shrink-wrapped boxes.
Even record stores generally let you play albums on a private turntable before you buy them.
It's just so weird to me that someone looking to buy a significant component for their desktop machine or whatever wouldn't do loads of research first. Buying a GPU, for example, during window shopping seems almost unhinged. But everyone's experience is different, and that's a good thing.
There's nothing stopping people from doing all of their Youtube research then walking into their Microcenter and buying it in person.
Its not like PC gamers who often use online stores have just forgotten to do any prior research when buying in store as opposed to online. So yeah I would do loads of research, then I'd go instore and buy it and look at what else they have on offer.
