Toys "R" Us offers the LEGO Castle Forest Ambush Set, model no. 70400, for $7.98. Choose in-store pickup to avoid the $5.99 shipping fee. That's $2 below our mention from last month and the lowest total price we've seen. (It's a current low by $3.) This 90-piece set includes an armored cart, forest base, and four minifigures.
