Streaming movie site affiliate PROMO code

Anybody know of a good streaming movie/TV affiliate program where I can use a code to give to potential customers, instead of setting up a site and link? A code that is like “first 30 days free” or 50% off would be key. Problem I see is sometimes the customer just goes straight to the site, but if they have to enter in a code to get 50% off or whatever, would think this would be better. Obviously the code would have to be linked to your affiliate program
