EG Auto Add to Cart Free Gift

This is the best ap in the Shopify ecosystem. We used to pay developers thousands of dollars to add customized "auto add to cart" features into our store. EG Auto Add enables staffers, including myself, with rudimentary technical skills to create custom action items. An example: if someone buys a bike, auto add a lock to the check out, at additional charge, or perhaps no charge etc. It solved ALL our "force add to cart," problems, and it's never failed.
