I helped shoot a wedding of a daughter of friends of mine last week, and I remember thinking the same when I ordered film for the wedding and saw the prices of 220 Portra. I ended up only purchasing 2 rolls for my Yashicamat, and I used a couple of other tlrs with 120 in them so I wouldn't have to change film so much. I've never been a trigger happy shooter but I really like 220, it's just so much more convenient especially at an event like a wedding. My friends paid for the film, of course, and there was an other photographer shooting digital, so they'll have the best of both worlds.
