I saw those the other day.
If you search "Craftsman Professional Use", they've listed 15 different Craftsman Industrial sets at discounted prices.

They have a bunch of sets of Deep Offset Box, Black Oxide, Stubbies, Ratcheting, Cross Force, Raised Panel, and Ignition Wrenches. Fifteen different sets in all, plus a three sets of Impact Sockets, and 1/2 Drive Accessory sets. All Industrial, All Made in the USA.
Worth a look, for the ******** craftsman made in the USA guy. I'm sure these are
get 'um while they got 'um type of sets. Once they are gone, then gone forever. If you have the coin to spend (most sets between $100-$200), now is the time to get them. They are all on sale, but not "Hot Buy", so you may be able to get some coupon codes to work for further price reduction.
