Walmart offers the VTech Sit-to-Race Smart Wheels for $29. Choose in-store pickup to avoid the $4.97 shipping fee. That's the lowest total price we could find by $20, although we saw it for $13 less in December. It's designed for ages 6 to 36 months, plays 50+ sing-along songs, and can be used for sitting play, rocker, and ride-on fun.
