My flex came with a sticker which I stuck on the back window of my truck. Well, fast forward and now my truck wears a bed topper and the sticker was, well, stuck. So I emailed Aero asking them how much for new stickers. Debbie replied and asked for my address and then threw some in the mail for me, free of charge. Now I realize that's a little thing, but little things go a long way. Thanks Debbie!
