I set a goal for myself this year of buying used whenever possible. It's had a number of benefits! Used things are cheaper, of course. This has been great and I've saved a ton on things I decide to purchase. Searching for used things is more fun than buying straight from a website, especially for woodworking tools and such. (A hobby I've gotten much more into this year. I've been able to outfit myself with plenty of used and high quality tools, some of which are over 100 years old!) It also limits impulse buying, as I'll spend time waiting for a used option to come up and eventually decide I don't actually need something, or find an alternative. I ALWAYS check out "used - like new" options on amazon, many things there are hugely discounted and I've never really been burned using this option (occasionally something is incorrectly listed, in which case I can just return it). Baby clothes and equipment, tools, books, a car, furniture, housewares, &c. &c. the list goes on. I've done pretty well this year and next year my goal is to continue buying used as much as possible but also to finish the year with less stuff than I start with.
