Where can I get 4x window deals for my Rover Cityrover Sprite?

I am desperately after 4 window seals for my 2004 Rover Cityrover Sprite (2 front and 2 rear). They are the seals that sit in between the window and the door. They have a strip of felt along them which sits next to the window to stop the rain entering the inside of the doors. I have gone direct to a Rover supplier and they want 拢90 + delivery for the them which I think is real expensive for 4 pieces of rubber! Any one help?|||Try kit car suppliers - they may have weatherstrips that are the same in stock.
