EDIT #3: (isn't this fun…) The box has been removed and the sign up form is crashing. I'll keep checking, but I think we Hiffed this.
EDIT #2: I found another link. Click on the yellow “Free Blade Offer” box in the lower left.
EDIT: Link has been fixed. That was weird.
Look, I know the holidays can make us all a little crazy. But please promise not to use this free Bosch oscillating blade to do anything stupid, okay?
