For Rent the Runway's unlimited "Try to Buy" feature, we user-tested the app and discovered that our users were accidentally tapping the buy button on the modal. As a result they were frustrated because they ended up with unwanted items and had to call customer service to have this resolved. To mitigate this, we added a safety feature - the "swipe to confirm" button that requires a much more deliberate swiping action. The user has to swipe further than the mid point threshold and then tap to complete the purchase.
