Goodwill---I must visit every single one in every town I set foot in.
ReStore---Goodwill's furniture counterpart. I love it and browse almost every weekend fantasizing about what I could rehome once I no longer have a roommate.
BigLots, Ross, TjMaxx---any discount/cheap store....yeah
I am a sucker for thrifting. It satisfies my need to shope without putting a huge dent in my wallet.

And, it makes me happy
