The Sunglasses Scam

That's exactly what Apple does ;-)

I find it a great lesson about the topic and in addition you showed an applied example in a real economy (MMO); I wonder if there are much more skills targeting those cognitive "bugs" that we as humans experience subjectively.

EDIT: actually... is this the only think that the book teaches?

I remember seeing lots of sunglasses listed like this, and wondering WTF was going on. It made no sense to me why there were a bunch of oddly priced sunglasses. either I ran into your experiment a bunch of times, or you started a trend ;)
