I bought buttermilk from WM a few weeks ago. A price didn't come up when the cashier scanned it, so she asked me how much it was. I hadn't even paid attention, so didn't know. She actually asked me how much I wanted to pay!!! I thought she was joking at first and said "how about nothing?" But, she was very, very serious. I finally just said, "How about $1.29?" Sold! lol
