Yeah, I’ve been throwing AARP stuff out for years. Also like to return postage paid envelopes empty when I am lucky enough to get them....
FReepers in AARP threads many months ago talked about how they like to FILL UP the return postage paid envelopes as full as possible and send them in, so they would have to pay more postage than expected. Use your imagination as to what to put in them (paper items, nothing dangerous or overly offensive, please).
