Hi there, i would love to have an option to include video at the description of a product.
i need the same thing… but since no answer since nov 22 … 
i need to link youtube videos on the description or on the page of a specific product and not the same video on all the different products… in fact, if somebody tell me it’s not possible with Wix … then i think me and my website will go elsewhere where it’s possible … 
It’s codable. It’s not a native Wix Stores app feature.
You can embed any store app on a Wix website. You don’t have to use the Wix Stores app built by Wix.
