Anyone can reuse old fully workable products in their every day life, it really is super easy and in many cases can be cheaper. While I do go occasionally go into thrift or antique stores, I also hit up garage sales, but my main source is ebay.

Besides the good feeling from putting something back into service that would other wise be junked there can be some serious nostalgia involved. Examples, I have a Toastmaster 1b16 fully automatic toaster like my grandparents had in the 50s, works perfect regardless how many slices pass through it. Old glass plates (morgantown, crinkle, etc) that we use every day for eating. Milk glass spice dispensers, salt & pepper, and old glass water containers in the fridge for ice tea. You can even buy old tupperware or ceramic and glass storage for the refrigerator. My favorite has to be a the vintage fans, a six bladed brass Emerson (blades look like ship propeller) is flawless in use and over a hundred years old.

About the only things I won't use are higher tech electronics, efficiency aside the older items may not even be usable because of software or serviceability
