Before hitting the cart, there is an offer to save a certain amount on the actual product if they sign up for a subscription. The No and Yes buttons were ordered intuitively backwards: Yes then No. Usually the primary button — the one you want them to click — is on the right.
Swapping the order of the buttons is a more intuitive arrangement - usually the primary button is on the right. This will increase CVR and increase the offer take rate.
Annual Revenue Increase: $370k
Overall Increase in CVR: 2%
Other Notes
Although a 2% increase in CVR isn't crazy good, the real success of this test is that more users are taking the offer. This increases LTV because of the monthly subscription.
