this is the 2nd time in as many mths. group of door knockers rampage through the streets claiming to replace existing globes with their energy efficient light bulbs for the entire house, FOR FREE, with no catch! "up to a thousands globes, if you have that many..." sounds great but like last time i'm hesitant to let someone who has just "cold called" into the house. oh, and they're not keen on leaving the free merch' by the door either. if that's not enough they claim that they have to change/install it themselves. so what gives? is this a state initiative or a scheme by some private company? yeah, yeah, i know, could've probed them more but i felt somewhat emasculated since i apparently can't change my own globes.
