Best websites for greeting cards

I have only used these a few times and most of the time it is for little reason beside to say hello. I usually use free greeting cards that are sent to the person through email and the person gets to view a flash card of my choosing with a message.

I would say my favorite site is by far: http://www.123greetings.com/

There are variety of different cards for choosing and the topics of these cards range wildly. Today for instance July 20th, 2007 they have a card for cow appreciation day. They have some outrageous holiday cards and I feel that this site is the best way to give someone a treat.

Other than that, I would just type greeting cards or free greetings cards in your favorite search engine and you sure to get some nice site to send someone a card from or get ideas from.
