Are there Eurotunnel offers at the show?

DSB

I know there are generally DFDS ferry offers at the show which are usually beaten by CC offers,  but does anyone know if Eurotunnel have a similar offer. 

We've only used Eurotunnel once and that has been so long ago,  I really can't remember what happened.  We want a Eurotunnel booking as we hope to take the dog with us next summer.  Can't imagine leaving the dog in the car with all the strange movement and noises on the ferry so it will have to be the tunnel for us. 

The odd thing is that according to their website prices are not yet available for end of July into August.  Is it usual for tunnel prices still not to be fixed for the October show - and any offers?
