ToysRUs online is currently offering a variety of LEGO sets on sale for 30% off. Some stores may offer these deals as well. As many of the sets have been discounted already, potential savings could be higher. For example, the retired LEGO Movie Lord Business’ Evil Lair set is down to $39.19 (reg.$69.99) which works out to be 41% off.
