My Mother-In-Law is like a Yard Sale Goddess, I cringe when the phone rings on Saturday mornings cause it's usually her at a yard sale, and she needs a truck. So I have to go over to my brothers, get his truck and find this yard sale she's bought a new table and chairs, armoire, or something huge and heavy, and take it home for her.
She also loves Auctions, the last one she went to was at a storage unit. Before they open it, they have an Auction and if they get enough, it's over. She bought a 10 X 30 unit full of stuff for $150 a couple months ago. Great deal, got a Trek mountain bike(I took that off her hands), a Nice Solid Cherry bedroom set, a couple window air conditioners, and a ton of other stuff. and, she sold the two window units for $200 right there after she opened it.
