Walmart offers the LEGO City Police Heavy-Lift Helicopter, model no. 4439, for $34.98. Choose in-store pickup via Site-to-Store to dodge the $4.97 shipping fee. (Amazon charges the same with free shipping for its Prime members; at both sites all users can pad their orders over $35 to qualify for free shipping.) That's the lowest total price we could find by $5, although most stores charge around $50. This 393-piece set includes three mini-figures.
