Hi @crystaldionedes ,
I have created a blog post to achieve this feature[https://mangitmaharjan.com.np/transform-your-add-to-cart-button-into-a-view-on-amazon-button/]. Please follow the steps accordingly to add amazon button instead of Add to cart button.
You can preview the working version on https://a3vy79r5bwsj9wk2-41985048729.shopifypreview.com
Thank you
