9. Think secondhand.
Borrow, swap or hit garage sales and thrift stores. Make a habit of checking your local version of Freecycle, http://www.freecycle.org , a nonprofit network focused on “keeping good stuff out of landfills,” or check the listings for free and secondhand items on Craigslist.
This approach is at the core of the eco-friendly principles of reduce, reuse and recycle. It can make retirees feel good while protecting their pocketbook.
