If you have a nearby location that sell travel-sized Biotrue contact solution, then get this $2 coupon that will result in free Biotrue contact solution. I've never heard of this but I just saw a commercial on TV for it so it has to be legit.
Then again, anybody can run commercials now thanks to Google TV ads. Which reminds me – I need to make one for HIF! I'll be sure to let you know when to catch it at 5am on your local access channel.
