If making a trip to the Post Office is something you'd rather not be doing this time of the year, but still want to send holiday greetings to your friends and family, several online card sites can help you out. They all work on the principal of filling out a form on a website, choosing an image file and music before being sent out. They also have several holidays and special occasions to choose from, so you can still visit them once the holiday season is over.
We'll start out with this site--awesomecards.com. 3 pages of Christmas greetings are here plus the other holidays are sorted by month. This site--freewebcards.com--gives you the option of sending a recipe or poem along with your card. care2.com promotes their "environmentally friendly" way of sending Christmas cards.
