I don't order from amazon enough to justify prime, but a few times a year I sign up for a free subscription for a couple weeks or so.

The prices on amazon are comparable to what I see elsewhere for everything I've ordered. The thing that sets amazon apart is that their delivery is blazing fast compared to everyone else. Yes, the reviews are always a little suspect, if I see tons of empty 5 star reviews, I suspect the product, but in general, I've been satisfied with my purchases.
