Amazon Prime is like an ever-expanding swiss army knife. With today's announcement of unlimited photo storage for all Prime subscribers, the list of things you get with one $99/year subscription has grown again. Here;s what you get for your $99:

• Free upgrade to 2 day shipping on all purchases shipped by Amazon
• Instant Video, a Netflix competitor
• Unlimited Music, a Spotify competitor
• Free books thorough your Kindle
• Unlimited photo storage

That's really incredible, considering that buying everything separately would cost you hundreds of dollars more each year.
