Does anyone know what I do to open :rolleyes: a thrift shop?

A normal thrift shop gives at least the impression of working with a charity of some kind ( at least locally here it does)

There are second hand or used merchanise stores or flea market type stores.

But you get a business license, rent a space, get insurance, buy the items you are going to sell and go into business,
