Westside Woodworks review for Hulk Product Options

I used this app for some months, then I happened to pay special attention to an order and realized it was adding options to customers carts but sometimes not charging them. Apparently the app is not compatible with the "Buy Now" button which is - I would argue - an important button on a Shopify website. All my customers who used 'Buy Now' instead of 'Add to Cart' would get the options for free. Hulk Apps were very aware of this and told me to remove the buy buttons from my website. I chose to remove this app instead. I think it was quite irresponsible for them to put this app out there with this known bug.
