I've been to interviews with other students who have made multiple deposits. I know I would have, but I just couldnt afford it. For me it was probably best that I didnt. It was hard enough to let certain schools go, it would have been even harder trying to decide now.
One good piece of info that a doctor told me was that it's more stressful for people who sit on the fence and cant decide, then for people to make the wrong choice. Those choices that are really important, like do or die decisions; those are pretty black and white for people. Its the little things that people get so worked up about. Basically optometry school is optometry school were ever you go.
