Acu-Copy is a photocopy store with, reputedly, the cheapest rates in town. Given a couple of days to work on it they will copy coursepaks no-questions-asked for much less than the cost of buying them fresh. Copies start at $0.04/page and go up depending on wether the material is bound, requires holes, etc.

Acu-copy is located just west of UM Central Campus on East William Street.

Useful place.
