According to the US Census Bureau, Americans send 1.9 billion holiday cards to friends and family each year. With the economy in the dumps and an ever-increasing need to cut back on energy/natural resources, why not do your part by sending e-cards this year.
Electronic cards are a convenient, green, and economic alternative to traditional greetings cards. Widely available across the interwebs, most e-card sites (i.e. Hallmark) offer at least a few free options.
