I just got some junk mail from that illegal alien loving company, Bank of America. Inside this junk mail is an evelope with "no postage neccessary if mailed in the United States." (notice it says nothing about Mexico... hmmmm)
This means that BofA pays the postage. Now I could throw this envelope away... or I could fill it full of washers and mail it back with a note indicating that their support of illegal aliens has not only assured that I will never do business with them but that it has now cost them a few bucks postage!
