That's a surprisingly interesting marketing deep dive. My better read than I expected.
The IKEA maze and food court are obvious, but the decoy pricing I did not know about it. It's a famous example with respect to magazine pricing (I think from Predictably Irrational). But I didn't realize IKEA was doing it. Also the "price first, design second" is something I was vaguely aware of, but I don't think I fully appreciated it.
