This would make a good sticker for all out-going snail mail...ie: postage paid return envelopes from credit card offers stuffed with their own sh*t, anything from AARP, any political junk mail from the RINOs asking for $$$-— but, send WITHOUT a return address! (and, cut off any code numbers on the postage paid return envelopes before sending back.)
(Good sticker for a LOT of uses. Thanks!)
