Thanks for reaching out here! That is a great question.
Great idea to add this feature! A sticky "Add to Cart" button serves the main purpose of simplifying the purchasing process for customers. By remaining fixed in place, the button allows users to easily add items to their carts regardless of their position on the page. This convenience plays a crucial role in boosting conversion rates and minimizing friction throughout the entire buying journey.
There are many options in our App Store here, so I would encourage you to look through those options to see what suits your store best. I’m sure you would find many suitable options.
Otherwise, if you’d like to edit theme code directly then I can share a video tutorial that was accepted as a solution on a different thread. Tutorial is done on Dawn theme, but it can definitely serve as a rough guide.
Just a reminder, if you’re using Shopify free theme and your store has enough complimentary design time left, you can reach out to our Support team when you’re having trouble editing the theme code yourself. While there is no guarantee, our team can review change request and see if they customize this for you.
While I would love to assist you with the process further, I do not have access to your store's specific information over social media due to our strict authentication policy. However, we’d be happy to continue assisting you through our Help Center. Please visit this page and log in to your account to create a support request.
Finally, hiring a Shopify Expert who can do this on your behalf is another option to consider. Let me know if that helps.
