Kmart is having a “Buy 2 Get One Free” sale on Lego building sets until April 3, 2010. Their selection is not great, but if they’ve got what you’re looking for, the prices are pretty good to begin with. Use the code “springtoy50” for an extra $5 off on the website. The coupon is only good through April 3, 2010 as well! I just used it, and it works!!!
