You misunderstand. I was considering the free trial but didn't sign up. Then they confirmed I had bought a 1 year subscription, which I hadn't.
I have been using Amazon for 15 years, and have bought thousands of items, so I am not a novice. In November I was buying an item for £6. At checkout Amazon flashed up that if I spent another £4 that the delivery was free. So I changed the quantity to 2 and got free delivery. It seemed to be that which activated my purchase of a Prime 1 year subscription. I had no idea that I was signing up to Prime, so I consider it was trickery.
