The charity shops in my area are not very good for clothes. People keep things longer here, so the clothes you find are generally a decade out of style and not in very good shape. I do, however, buy kitchen items and used books from those places often.

I love browsing antique shops, but seldom buy.

Used bookstores are my jam. One of the first things I do when checking out a new city is locate the good used bookstores. New bookstores are nice too, but I rarely buy new books full price.
