My biking mileage was horrible last month, for a couple of complainypants reasons, but I just found out today that my employer refunds the mandatory parking fee (taken out of each paycheck) for every week that I bike to work at least one day. Bi-weekly paycheck, $6 per paycheck for parking - If I manage to bike in at least once a week for 6 months, that is... about $75 in free money (on top of the money I save on gas, upkeep, etc). Not tons of money, but I'd rather have that $75 of my salary than let my employer have it. We submit our calendars quarterly, so it looks like I'll be able to include June on the next one.
