Renault World Series

[Arbs]

So the Renault World Series is returning to silverstone again this year. I went a few years ago and it was fantastic. Every level of Renault racing was there and will be again. Last time I went I managed to get free tickets through Renault, is this still the case? I have had a look and tickets are £12 at the moment which isn't bad for the quality. But was wondering if anyone knew or has a way of getting free tickets.
Also is anyone else attending this year?
