The Buy Button add-on connects your blog, website, or email campaign to your X-Cart-based store and is an easy-to-use and powerful tool for allowing your customers to buy from you on different websites. You can use Buy buttons to sell products on WordPress, Tilda, Wix, your website, or wherever you've already built an audience online. Product cards with the Buy buttons always show the actual product name and price, even if you modify them on your storefront.
After installing the Buy Button add-on in your online store, you can create a new Buy button for a product. As a result, you get either a code snippet to embed in the webpage's source HTML or a URL to add to your email campaign. After you embed it, the code displays a Buy button.
Usually, the Buy Button add-on comes installed and enabled in all X-Cart editions.
See Installing Add-ons from X-Cart App Store for guidance if it is not.
