Some of your "analysts" seem like they can be net loss. I'm thinking someone who only ever buys the groceries that are at least 50% off, having no particular recipe in mind so no need to combine with regular-price items. Grabs them by the truckload when the sale comes, then lives off their freezer for months.
I don't know if it's common to do it so perfectly though.
