Smart OTC Shop review for EPA‑ Easy Product Addons

I was looking for a simple way for customers to see related products on a product page and add those directly to the cart with the same click on the add-to-cart-button. The app "Product Addons" does exatly that. It instantly led to an increase of related product sales after I setup the app. The SpiceGems team was very kind and helpful. They showed me some more design examples and added customizations within hours. It's fantastic! Can absolutely recommend this app.
