As Stefanie mentioned today, some of you might consider joining forces and splitting a brick of film from B&H. If you buy a brick of 50 rolls (enough for 3 of you for the whole semester), the price before shipping is $199.50 (that's $4 per roll, or 30% cheaper than the bookstore). That's a good deal:
Remember, the student packs of paper and film at the bookstore are a smart buy: 2 rolls of 400 speed HP5, 36 exposures, and a package of 20 sheets of paper for about $23. Go load up while you can.
