Also, if you can change the framing so the decision becomes 'which option should I go for?' instead of 'do I want to buy this at all?' then that's a valuable bit of sleight of hand. But it comes with the risk of decision fatigue
Sure, this might be the worth of the features, but then I might get frustrated: "I want features X and Z, but they are only in the most expensive tier. In the cheaper one I can get just X, or X and Y. So now I have to pay for X, Y, Z although I only need X and Z."
Another example: johnreed fitness gym offers three tiers. They are basically the same, but give you more flexibility in where you train. If you are a member for one year, you move up one tier for the same price. It's not clear whether or not my contract would get cheaper if I start at the highest and after a year move to the price of one lower.
So basically they made me work and think a lot just about pricing for some service I actually want because I don't want to think about it. Which made me choose another gym altogether.
