What are some things you mostly buy secondhand, and some things you prefer to buy new?

Examples for me of things I only buy secondhand if I can help it: Clothing like shirts, sweaters, dresses, jackets, and pants or skirts. I will sometimes buy a coat secondhand but I generally just wear the one I bought new over a year ago that I'm hoping will last me for a while. I tend to buy shoes new, and of course underclothes.

I'm wondering if there are non-clothing items you only buy secondhand, and also if there are items you would never buy secondhand.
