Pruct sku

What do you mean by sku product?

If I understand your question, you can add any product whatever you like.

Thanks for making me clear. Yes, you can do it but need some development knowledge to edit the popup template.

We are not offering any customization support with this free plugin.
If you don’t know PHP then you need to hire someone.
