Actually the Pork loins you get in your part of PA probably don't have Tenderloins included. They lay along side, but not within the loin, so they probably weren't in your CB.
I know the Pork Loins I get are about 9 or 10 pounds, and the Tenderloins aren't part of them. You have to buy them separate.
Bear
They are not hard to find around here if you have a lot of money. However, they go on sale for a decent price on occasion. When they do, they are hard to resist.
I see them separate all the time.
Expensive little things.
