Query: A very disappointing bait and switch by amazon

I've always had good experiences with Amazon until now, but having just signed up for Amazon Prime--in part so that we could watch free episodes of Midsomer Murders--I see that they are suddenly charging a hefty fee to watch it--a very disappointing bait and switch. Fortunately, I'm still within my 30 day free trial period for Prime, so I will probably drop it.
