I went to an estate sale like that recently. As people would bring things up to buy, the lady would tell them that she wasn't sure she wanted to sell it, and had a huge pile of things she had decided to keep. After this happen 2 or 3 times I just left. Didn't see any reason to waste my time if she was just going to tell me she was going to keep whatever I wanted to buy. Some people are just ODD!!!!!!!!!
