Amazon and Ebay have also saved me a fortune over the years.

Same here. Both have great deals on used stuff. It's easier to buy used now than it ever has been.

Even new stuff is sometimes deeply discounted on Amazon.

I have gotten decent buys on some used clothing on eBay, but for many things it is a seller's market. You are competing with millions of buyers all over the world. However, that means that it is the place to sell things you no longer need.

Really good deals can sometimes be found at yard sales and consignment shops. Even better is the town dump, where you can sometimes find desks, file cabinets, lawn mowers, etc. for nothing.
