Just picked up a RoadID since I try and play chicken with cars (and them with me) on occasion. They sent me an email for a $1 off for up to 20 orders before 03/13/2010. I'll try and remember to remove this post once the month is up since the coupon code will be invalid. $1 isn't much, but it almost covers shipping. The code is: ThanksJohn617988
BTW, Sasha, I refreshed the page of the blog several times until the RoadID ad came up to click on it. Hopefully you get $0.01 or more for my click and purchase.
