I have an extra Chicago city sticker for a bike and a car. I ordered online, and the bungheads charged me twice, so I will have extras. Of course there's no number to call on the website to fix this, and I'm sure that they'll respond to my email quickly.
If anyone needs either or both, let me know. I'll sell them for the regular $75 for the car, and $45 for the bike. After today the late fee would be an extra $30 if purchased from the city.
