>Where a trader has several country versions of the same website, such as a webshop selling products to different countries across the EU, you should be able to choose to view which version you visit. You must give your permission to be redirected to a specific country version of the website. You should also be able to change your choice at any time.

> However, there is no possible justification for differences in access to goods or services for customers from different EU countries in the following three situations:

> sale of electronically supplied services (excluding copyright protected content) – such as cloud computing services, or website hosting
> sale of services provided in a specific location – for example hotel bookings, car hire, tickets for entry to theme parks
