My local kid's consignment shop sells them and BST groups advertise them too. Just wondering if you would buy or even use (for free) a used car seat?

I put the Chicco Next Fit into my car and my Maxi Cosi got the boot. The straps on the Cosi seemed to weigh and constrict LO and taking out the Tiny Fit insert didn't help. Probably user error. Well, DH bought another Chicco since I wasn't going to give his back. Ha!

The Cosi is good for another 8 years. Are car seats something people use used?
