Some of my favorite flips include:
I paid a buck for a sealed He-Man figure that I thought was a reissue at a yard sale. Turns out it was vintage, sold for $150.
I bought a sealed pair of Twilight dolls at a thrift store for anout ten bucks. I was finally given a single reason to like the franchise when they sold for $225.
I picked up a vintage brass bathroom set for about three bucks at a thrift store. Sold it off in pieces for a total of about $150.
I have more but Ill let others brag now.
