Wal-Mart and Target stores in America are now offering 30-50% off select LEGO such as Uruk-hai Army for $20.97 (reg.$29.99). Some people even reported finding LEGO Series Minifigures for $1 (reg.$2.99) at Wal-Mart. Deals are YMMV which means selection and prices may vary (i.e your local store may not have a single product discounted at all). Though, most people are having more luck at Wal-Mart than Target.
