Hi I bought something from Amazon and when I went to checkout it said you can have a 1 months free Amazon Prime deal. I clicked on it and I was automatically signed up. I look at my delivery cost and it was £0 and my delivery is going to come the next day. Im Happy! But remeber to cancell it before your month is over!
If there is no banner stating the free trial, go to your account settings and near the bottom is the option for amazon prime management. You may be surprised to find an offer of a free 1 months trial waiting for you.
