Buyers remorse is also bad for business. If you feel the extra $700 you spent on top of the, relatively, high sticker price of your laptop* wasn't worth it, you're not as likely to be a return customer. That's my experience from the days I spent selling swords ($300-$5000 range for reference) in a martial arts supply shop.

For some people yes. My best friend is that way. Charge a lot for it and he'll love it forever. I point this out to him but he remains unfazed. I'm not so easily convinced that price = quality ;).
