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）

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.

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.

After testing the app for two weeks and also testing similar apps (20+) I can say "Product Options Variant Option" is one of the better product option apps here on shopify.
Its great, that options will be stored as a draft order, so it is not getting messy. Unfortunately with the app all options will be handled as a seperate fullfillment with its own tracking number. When I have sold one product with 4 options, shopify tells me, that I have sold 5 products. It would be great if there will be an option to sum up the product with the options to one product and one fullfillment. Also a function to set the price to percent could be implemented (like Advanced Product Option - App) and the error messages not as javascript alerts. There are some bugs, but no cristical one, the support is fast and very helpful in solving problems, also the price is reasonable.
