Have you tried this?: 1. Get a box (not too large - just small enough to fit thru the door of the post offices package box - or better, use one of the USPS free shipping boxes) 2. Collect the junk mail, and put it in the box, sans any identifying information (this is important!) 3. As you collect the junk mail, keep back one of the pre-paid envelopes sent with some junk mail. 4. When the box is full, tape it up, and tape or glue the pre-paid envelope to the front. Alternatively, put the address of the postmaster general on the front. Leave the return address blank! 5. Take it to a random post office, and mail it. Use the outside boxes, and make sure not to be caught on any cameras (you may need to do a bit of looking around first) 6. Repeat as needed, paying attention to the previous step and not using the same post office each time. This is probably not completely legal - but if you do mail it to the postmaster general instead of using a pre-paid envelope, I think you can do so without needing to pay for a stamp or anything (can't recall). It might be very satisfying to do it once or twice, though. /ymmv, the above is for entertainment purposes only
