In this experiment, the font of the euro cents amount was made smaller. Additional copy was also added underneath the price reinforcing that tax was already included in the price. Impact on transactions was measured.

In this experiment, copy around an upsell was changed from using "optional" to "our recommendation for you". The idea was to recommend two upsells with more confidence. Impact on the two upsells (secure, and express) as well as overall transactions was measured.
