This may also be YMMV but I got a $25 off next purchase of $75 or more for spending more than $100 today. It's redeemable between 11/28/11 and 12/24/11 so it does have a window of use.
I was shopping because I had a friends wedding comming up tomorrow and this was my first experience at K&G but they had some really nice prices. Then again, I don't shop suits much so I could be wrong
