Canuck Canada review for Hulk Product Options

This app is really buggy and breaks out of the box shopify features in order to have to use their other tool in regards to discounts (hulk volume boost). And now new issue discovered, the options price increase does not reflect on checkout. Their real-time support is completely useless and i have to guide them where to find their own application information, i am a paid user the support is ridiculous. The only cool thing about it is the customization possible to the form itself on products and the flexibility of conditions. It just causes a huge problem for the checkout process
