Walked into the San Mateo (Hillsdale) store today and found a 7-piece, 3/8" drive, 6 point, Made in the USA, metric flex socket set on sale for $27. Its like this one:

This set comes with 10, 11, 12, 13, 15, 17 and 19 mm flex sockets. A nice set for the price, but really, who uses an 11mm? Really? They couldn't have substitute a 14mm instead?! Must have been spec'ed by someone who never worked on cars....Nevertheless, the sales person told me he expected the remaining loose sockets to go on sale soon. If so, I'll be looking for that 14mm flex....Good Luck!
