How do I sell items from my CMS and not the product list?

How do I sell items from my cms instead of adding products to the Wix store and selling it from there? I have tried custom forms, adding an add to cart button to my dynamic page connected to my cms, and adding items from my custom cms to my Wix Stores/Products cms with Velo. I can’t get these solutions to work. I have tried on free and premium plans past the light plan.

You’re gonna have to basically recreate a shopping experience using repeaters, a cart page using the data stored for that session and then checkout options using wix-pay.

There’s quite a bit of code involved in this process.

What is your use case. And why not use wixstores?
