Thanks to Pater for pointing this one out. Through January 24, Jos. A. Bank is selling their Signature Gold suits for 70% off list (usually $1100), that is, about $330. This is as good an opportunity as you will ever have, particularly if you are The Guy Who Only Needs One Suit. The value you obtain for the extra $110 more than you'd pay for an Executive model on sale--indeed, the value you obtain for $330 period--is immeasurable. We are pretty sure that Hickey Freeman manufactures the Signature Gold suits on JAB's behalf.
As usual, I would recommend going to a brick-and-mortar so you can start to build a rapport with a salesman and make sure the suit fits properly.
