Walmart offers the LEGO Ninjago Ultra Stealth Raider for $69.05. Opt for in-store pickup to cut that to $67.08. (Amazon has it for the same with free shipping.) That's the lowest price we could find by $3, although most stores charge around $80 or more. It includes seven mini-figures, the raider vehicle, twin 6-stud rapid shooters, two spring-loaded shooters, six detachable golden ninja swords, and two golden shurikens.

Update: The price has dropped to $67.08 before in-cart discount, $65.11 after. Amazon is now a few bucks more.
