Maybe if you were running a service, you'd be better off evaluating how well your prices are doing by selling multiple plans and paying attention to their relative sales behind the scenes. If only your cheapest plan is selling, you're probably priced to high, and if your cheapest plan is ignored, you might be priced to low.

I don't know if the higher price sending a signal is all that relevant, since you would basically just be changing the price in whatever direction will maximize revenue. If the high-value signals end up producing more or less sales, you would just see that in the results.

You would definitely mix up the whole perception of your prices though.
