All of these ideas were discussed in a pricing seminar I had in the early 90s.

For anyone who has studied pricing the least bit, these ideas, even put all into one page, are not particularly novel.

The hard part, imho, is to get people to actually believe these ideas work. As replies on this thread show, there are doubters even though these ideas are just pricing fundamentals.

Yeah I was surprised by how this article tried to oversell itself as if it was revealing some fundamental secret. This stuff is marketing and pricing 101. Reading that the author thinks presenting it in this way is somehow novel is a red flag for me that they aren't experts or qualified to be presenting this material, since experts and practitioners should be more than familiar enough with these tactics to know that this is like the most basic set of pricing tactics anyone would learn.

What would be more powerful is a "formula" for figuring out the exact willingness to pay for a product to know what number to anchor/distract around as your target number. Figuring out willingness to pay is one of the actually hardest problems out there that a never before seen formula would be interesting for. But like, the anchoring effect? That's not even marketing 101, that's covered in AP psychology
