A shorter word to describe a secondhand marketplace?

I am looking if there is a word that describe a place where people can selling/buying used things.

For example: Seller come to sell their old things which they never use it anymore for whoever need it, for a cheaper price. And buyer come to buy stuffs for lower price instead of buying expensive new one.

I have found word "thrift shop" so far. However, it doesn't look like exactly same meaning as above. (Correct me if I'm wrong)

Thanks all!
