We would shop at Goodwill a few times a year as youngsters.
Mostly my mom picked up small appliances and household stuff that needed replacing like toasters, lamps, coffee table and such.
Buying someone else clothes was a big NO way
and much to my chagrin as an avid reader she
would not allow us to buy used books.
I mean supposedly they washed all the clothes but
them books gotta be filthy as hell and how you gonna
clean paper, we did go to the library a lot so maybe
that had something to do with my many allergies
