Speaking from experience, you're most likely to be upsold if you don't know what you're looking for. For example, I've been upsold when I was buying a printer. I know nothing about printers, so much of the purpose of going to Best Buy was to see what they had and what the salesperson recommended.

Most HN members are unlikely to be upsold due to high technical knowledge. You are probably more likely to have done research ahead of time and know exactly what you're looking for.
