Thanks for your store website URL. That’s a really awesome product you’re selling!
It sounds like you want to add a function to your website so that you can start selling right away. If that’s right, I recommend using the Buy Button on your website.
A Buy Button helps you add products to your external blog or website and is like a shortcut for buying your products. It helps customers stay on your page instead of navigating to a different website to checkout. Buy Buttons can show product pictures, descriptions, and prices, all while letting customers purchase products without leaving the website. Any updates for your Buy Button will appear with all the details in your Shopify admin.
Check out our help doc to learn more: Buy Button.
