I've had a Prime membership for three years now and I love it. I bought my D7000 in a brick & mortar store, because they helped me out a lot with looking at different models and such, but most of my other gear has come from Amazon. The free shipping is great, and only $3.99 for next day delivery is hard to beat. I've ordered some weighty items (a bedframe and a nightstand to name a couple) and the free two-day shipping saved me quite a bit. It was money when I was deployed too, even though it took longer than two days.
