Brando, IMHO your language is too stong. When the solicitation contains a SASE? Send the material back to them. Include a very polite note thanking them for that offer, but you choose to decline. Nevertheless, you know that printing such material must be expensive, so you're returning it to them, so they could pass it on to someone who could benefit. Or, should they REALLY p!ss you off? Glue the envelope to a brick, drop it in a mailbox. "First class return postage guaranteed", right????
