Not that the author doesn't have a point, but isn't Amazon Prime totally worth it if you order more than 3-4 times a year? I probably order something from Amazon once a month, if not more. On every other website I order from, I have to pay for shipping. Ordering something once a month could easily go over $100 in shipping costs. I mean, maybe Amazon is shifting things around to get you to sign up for Prime, but to me, it seems like a no-brainer anyway. Not to mention Amazon Prime Instant Video...
