e-commerce website- created using WP?

https://getshopped.org/showcase/
https://shopplugin.net/category/showcase/

Those are two showcases for a couple of popular ecommerce plugins. There are a lot more out there in the plugin directory or for sale on third party websites. A lot of them will have a showcase, so I would recommend finding a bunch of plugins and looking at their example sites. That way you can see exactly how it looks when someone designs it to work the way they want it.

Thanks =)
