I could just leave it there, but the majority of people need evidence to support that statement.
When I first signed up for Amazon Prime during its debut, all it covered was shipping services. Years Later, they added on Streaming and some kindle crap (i dunno, kindle-less). With the amount of items we (the family, friends and I) bought, it was definitely worth it. For an extra $20, I was hoping for some added bonus, but it would still be worth it in the end.
This calculator will give you an even better idea whatever or not Amazon Prime is for you. Rip off or not: http://slate.me/1hiN6nA
