I might go to thorpe park for my birthday...?

Does anyone know where I can get the 2 for 1 tickets to thorpe park, theres gonna be 6 of us so I need 3 of the vouchers . And I dont want to pay with my card so Im talking about either printable ones where you can pay at the gate or ones that you can get from somewhere already on paper. I dunno if anyone else had this but in past years around this time they would give the 2 for 1 tickets in the post with local newspapers for thorpe park, chessington, alton towers etc. Does anyone know if they are till doing this?? Also whats the best place to eat at in Thorpe park??? Thanks for any answers :D x x x
