[Highland Park] Looking to Buy a Stroller

Hi neighbors...   My sister is looking to buy a gently used Snap'n Go style stroller that works for a Chicco Key Fit/Key Fit 30 car seat...  it can be either the Snap'n Go brand or the Chicco brand, as long as it fits....   Please let me know if you or someone you know has one to sell. Thanks, Lydia
