Amazon is a great place to buy film. Fresh and selection isn't half bad. They have most of the Kodak, Fuji and Ilford current products. If you are a prime member, most of it comes with free two-day shipping. College students can (as of last fall anyway) get a free 1 year prime membership.
"I only wanted Uncle Vern standing by his new car (a Hudson) on a clear day. I got him and the car. I also got a bit of Aunt Mary's laundry, and Beau Jack, the dog, peeing on a fence, and a row of potted tuberous begonias on the porch and 78 trees and a million pebbles in the driveway and more. It's a generous medium, photography." -- Lee Friedlander
