Plus another place that I recently found was Career Builder "Monk-E-Mail". You first pick your "Chimp"...Pick your Accessories...Pick your location...the last part is hilarious, you personalize your card. Now I am talking you can talk into a mic, or type text in. You can even have an English accent! Plus the eyes of your character follow your mouse around!
Go send a card...I am sure you can create one for any occasion!
