Right now I found Lodge Original Finish 6-Quart Cast-Iron Camp Dutch Oven which is a 12" reg. depth for $30.15 with free shipping. It is on clearance so it won't last long. But seems to me if you want that size it is a good deal. I hit others on clearance last week, so I don't know if there is more or not as haven't checked whole web site.
