I pop into my local Sears every now and then, hoping to catch a Knipex deal like that. It hasn't happened yet though.
All of the open stock USA wrenches and sockets have quickly disappeared for overseas stuff, but I still go and see whats left of the rebranded stuff; Wilde/Mayhew (pry bars, scrapers), Ullman (picks), Western Forge (pliers, punches, chisels, screwdrivers). While I'm there I usually grab a pack or two of studs for the plastic VIM/Craftsman socket rails.
Go to sears dot com, type in knipex then sort by price. You won't find a deal quite like SweetD posted but a few are marked down pretty nicely. If you have SYW points and or coupons, you can get some at really good prices.
