I'm stuck. Anyone know a good example of a trade and retail website

Didn't think about the SEO part. So here's another example that will be more fitting. They are using "tabs" for switching type instead. 
https://www.netonnet.se/

Look at the top right corner "Privat" and "Företag". (image attached)

Here in Sweden I haven't seen any big companies with a retail/business e-shop got a sticky menu. You are always changing what type of customer you are at the top right corner and somethings in the footer (and the top right corner of course). If they don't have a button. You just know taxes are included and you select at checkout.

But I don't know your market so...

Hello Jreklund,

We really like the design https://www.netonnet.se/ , do you know if it was all done with CI?
We are developing a rental/sell marketplace with CI which is www.roynac.com, and wanted to know if you know any other CI marketplace or/and ecommerce, developed recently that you might want to share the ides...

Regards,
Robert
