Whether it's your local metaphysical shop, farmer's market, or hardware store, buying local is an easy path to intentional spending. The 3/50 Project is my preferred method of encouraging local spending, because once you get past the sometimes-confusing name, it's an easy way to redirect existing money to local businesses.
The 3/50 concept is this: take fifty bucks each month, and spread it around three local businesses instead of using it at chain stores, franchises, or online. The project has a pretty specific definition of local business that focuses on the amount of money which stays in the community. One thing I like about the concept is that it stresses balance -- don't avoid big-box stores entirely, if that's where you get the best deals on some items, but do spend some money in businesses owned and operated by your neighbors.
