Mytyres - business model and German terms/conditions?

[plg]

I'm after some winter tyres so looking around at prices, etc.

Mytyres seem to have the range and a lot of people seem to use them. Looking into the company, would I be right in thinking that they act more as a broker or agent than anything else?

Their UK contact address (http://www.mytyres.co.uk/Contact.html) is for orders only - no returns to that address (assuming courier collects).

So I'm assuming without the warehouse and cash/cost issues that they act as an agent for selected brands, taking the transaction and delivery risk on behalf of the wholesalers (around Europe?) but not actually carrying any stock?

But although they are providing the operating details of a UK ltd company they are suggesting that all terms and conditions are subject to German law?

Thoughts - is this right?
