I saw this hilarious idea on Regis and Kelly the other morning. To save money on Christmas cards, cut or tear a cardboard box into postcard-sized rectangles. Address one side, and add a stamp. On the reverse side, write or stamp, or apply a label that reads,
Money is tight
and times are hard,
so here's your darn
old Christmas card.
(Of course, instead of 'darn old', you could write thrifty.) This idea cracked me up and made me wish I hadn't already gotten all of my cards signed. =)
