Toys"R"Us offers the Diggin Active Skootcase Ride-On Luggage in Blue or Pink for $24.39. Opt for in-store pickup where available to dodge the $5.99 shipping fee. (Alternatively, pad your order to over $29 to bag free shipping.) That's about a buck under our March mention, the lowest price we've seen, and the best deal we could find today by $9. It functions as a ride-on and a suitcase and features fully functional steering and internal storage.
Note: Red is available for $24.98.
