I will pay up to 100% markup on things if:

1) I know there's a chance I'll need customer service with that thing 2) The company I'm buying from has actually good customer service.

the biggest companies in the world (microsoft, google, netflix, amazon, facebook) have pretty awful customer service no imo. What kinds of companies are you talking about?

The world is so much more than these few tech giants where everybody at HN works.

Then give examples. You can't give 0 examples (while the comment you're replying to gave a list) and pretend you know better at the same time.

For example Apple is famous for their good customer service, and it seems that worked out well for them.
