I’m not clear what you mean, but I understand the concept of being your own warranty backer. This is different - I would have bought this screwdriver with a visa, if I didn’t have that Amex.

The Amex makes me confident I have recourse. Is your point that I would spend less if I didn’t have that confidence? I suppose so, but I’d actually rather prefer having that confident experience rather than feeling insecure or like I got ripped off.

That’s real value, and I don’t mind if it means I buy an extra tool here and there. Especially if I can get some extra refunds.
