My cousin just gave us her daughter's old Britax Marathon car seat, but it has a yellow cover with flowers...not that it matters that much, but I'd rather a more gender neutral cover. It's a long shot, but I was wondering if anyone had a gender neutral cover for this seat that they may be looking to get rid of? The ones on the website are $70! More than I was expecting (although still cheaper than buying a new seat!). Thanks!
