A great way to support your local library and find good deals on books is to go to library book sales. Most libraries have them multiple times each year and the prices are very reasonable. Plus, the money goes back into the library to support buying new books or community resources.
Do you find yourself buying the same magazine at the newsstand or supermarket checkout line every month? Go ahead and subscribe to it. Most subscriptions save you at least 50% off the cover price. On the other hand, don't renew magazine subscriptions that you rarely find time to read.
