K-Mart stores in America are having a 50% off sale on already reduced clearance toys including LEGO. Excludes Spring & Seasonal toys. Final discount will be taken off at the cashier register. There are also some points and coupons that could potentially stack as well. Details along with some of the reported finds are available in the forum. Thanks to forum member minifigW for the tip!
As always, prices and selection may vary depending on your location. You may want to drop by your local Kmart store to have a look.
