That's a very reasonably reply.

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.
