I signed up for a 30-day free trial of Amazon Prime about a week ago. I have to say that I love it. Packages arrive two days after ordering, definitely fun during the Christmas shopping season.
They even make it easy to cancel before being charged the $79 annual fee right online. No need to call someone half-way around the world to get a high pressure sales pitch.
In summary, sign up for this stuff before the end of the year. It makes holiday shopping easier 🙂
