Keep Wall Street Occupied (by ransackedroom)

Well this is a pretty dandy idea. Send back all your credit card postage paid envelopes with OWS messaging in them. 

I would assume that those postage paid envelopes are only authorized for a 1-2 ounce rate, so putting wood in them is most likely to just get them rejected by the post office.
