Initially, the app was buggy when using a drawer cart style but the issues cleared up when I switched our cart to page style. I reached out to the developer when I was having issues and I never received a response, had to troubleshoot myself.
Easy to use, but I wish you could require customer to check a box before checkout., or at least notify me if they checkout with a negative answer.

App is OK...
Works great with native checkout, but doesn't work for PayPal
