In this experiment, the pricing of three software plans was consistently framed into a more comparable monthly context. Whereas the control version only showed the total prices for each plan, the variation showed both the total and monthly prices. Impact on sales was measured. 

In this experiment, a two plan pricing plan (standalone product with a higher collection set) was tested against a single plan one (only a collection set). Impact on clicks and total sales was measured.

In this experiment, a pricing plan selector was shifted from the very bottom of a long product page towards (almost) the top. Impact on any transactions or sales was measured.
