Piping Rock offers the Piping Rock Mega Potency Apple Cider Vinegar 600mg 200-Capsule Bottle for $6.63 plus $1.95 for shipping. That's tied with our mention from last week, $4 off list, and the lowest total price we've seen. It purports to help "flush your system" and support weight management regimens.
