I really love Prime, both for the free shipping as well as for shopping. I buy toilet tissue and paper towels by the case even though there are just the 2 of us. It is cheaper tha at the market. You do have to watch the prices but most times Amazon is competitive. I even sometimes buy cereal. I often use the Subscribe and Save option to save even more. You can always cancel your subscription after your first shipment. I need to look into the options for books more as I think you can borrow some for free.
