Ymq Product Options, Variants

アプリに問題を発見したのでサポートにメールで問い合わせると、比較的短時間で修正対応してくれました（英語でのやりとりです）

Support: 5/5 App: 4/5 - only because sometimes there are issues that require intervention to resolve and some of the text in the app is written in bad english. However, it is the best app for the price I have found so far and perfect for my shop since we custom make most of what we sell.

Great app for adding specialized variants. We've sadly had a few bugs to work out lately, but the app developers have been very responsive and have helped fix any issues. Highly recommend this app.
