I read that a lot of people end up with a free month or more on their membership because if their package doesn't show up within the two days and they notify amazon, they add an extra month to their membership and it actually happens a lot. I ordered two-day shipping on something just a couple months ago and it arrived late (they warned me it would) and they automatically refunded my whole shipping fee (I don't have prime).Last year I signed up for Amazon prime, I found that we hardly used it, so I was going to cancel, well I forgot and as of yesterday I'm a prime member again. Goodbye 100 dollar's. Not a great week to have that surprise.
