Walmart offers the LEGO Nexo Knights Moltor’s Lava Smasher, model no. 70313, for $11.98. (Toys”R”Us offers it for the same price.) Opt for in-store pickup to avoid the $5.99 shipping charge. That’s a buck under last September’s mention and the lowest price we could find by $7. It includes Moltor and Aaron Fox minfigures.
