April 2 Update: If you have VISA, you can get $25 off $125 too.
Forum member greanie2011 informs us that this week from April 1-7, Kmart USA will be offering BOGO 50% off on LEGO Star Wars, City and Hero Factory theme sets. Maximize your savings up to 25% off by purchasing sets of equal value. LEGO Friends City Park Cafe and Heartlake Dog Show will also be on sale for 15% off (thanks Nepenthe7). Note that there are no markups at Kmart so you are getting real savings.
Even better, there’s free shipping on orders above $39 and you can receive an extra $10 off $100 by using coupon code KTOYS10!
