MPO ‑ Multiple Product Options

I was hesitant to buy this app because the details aren't very clear on the page. But the developer was super responsive and helpful, answering my questions prior to purchase. After install, I was having trouble getting it to work in my theme, but again, they helped IMMEDIATELY so I could get up and running! If you run into some speed bumps at first, don't give up, I know they will help you. Most importantly, it is a great app to add one customization to any product(s). HIGHLY RECOMMEND.
