Is starting potty training on your mind? If so, check out this deal at Walmart. You can get The First Years Training Wheels Racer Potty System for just $15.99! I had something similar to this when my boys were little. They loved cars and it motivated them and made it fun to go potty.
This system is great because you can use it as a stand alone system and it can double as a potty seat on a larger toilet. Be sure to select free in-store pick up to avoid shipping fees. Otherwise orders of $35 or more will ship free.
