Build Your Own Orbit Toddler Stroller

Do you love the Orbit Stroller, but your kid to big for the infant car seat. Well there is the option of buying the chassis($485) and the stroller seat($180). Or the chassis($485), car seat base($180), and the toddler car seat($300). It will still cost you, but you won't have the unused infant seat. Now if I could just figure out where to buy just the car seat, which is the part I love. $180- $485
