Walmart offers the Fisher-Price Imaginext Remote Control Bat Bot, model no. BFT56, for $45.13. Opt for in-store pickup to avoid the $4.97 shipping fee. (Amazon charges the same with free shipping for Prime members.) That's $4 under our mention from last June and the lowest total pric we've seen. (It's the best price now by $5.) It features over 100 sound and light effects, remote control, Batman figure, and four launcher disks. The Bat Bot requires six AA batteries (included), while the remote control requires two AAA batteries (not included).
