Walmart offers the Little Tikes Splish Splash Sink & Stove for $14. (Amazon charges the same with free shipping for Prime members, albeit with a one to two day delay in processing.) Opt for in-store pickup to dodge the $4.97 shipping fee. That's the lowest total price we could find by $7. It features a working pump that provides water for washing the included plastic plates, cups, knives, and spoons.
