Amazon offers the Little Tikes Princess Cozy Coupe 30th Anniversary Ride-On for $39.90 with free shipping. (Walmart charges the same with in-store pickup.) That's the lowest total price we could find by $18, although we saw it for $2 less in April. It features a high seat back, rear storage, steering wheel with horn.
Note: Most orders placed via 2-day shipping by December 22 will arrive in time for Christmas, however since it may require an extra one to two days to process, Christmas delivery is not guaranteed.
