Three short videos on Pricing

I thought this would be interesting to post here for two reasons.

First, I imagine most HNers probably analyze prices as the most rational and analytical consumers in the world. It's good to get a reminder that the rest of the world doesn't do that.

Second, I thought it was interesting to see a VC (Harrison Metal) put together this kind of informational video. I would have liked them link to the reference material underneath the videos, but still pretty cool.
