SAE and IRC.
Yesterday I found out that both the return cards has been in my own home since August! My wife is subscribing to a women's magazine and somehow the envelopes got stuck between the pages of the magazine in the mail. By coincidence the magazine was never read but put away and forgotten until yesterday. When my wife grabbed it, the two unopened envelopes were revealed!
