Office Depot is doing a promotional event with HP in which the store will offer free electronics recycling through Labor Day for residents of the continental US.
According to the Office Depot web site there's a limit of one item at a time and they really mean PC equipment (eg, what they sell). No TVs and no appliances.
It's a good deal in any case, it normally costs $25-35 to legally dispose of CRT. Of course if I make the trip I'll buy something at Office Depot as well.
