I have about twenty pounds' worth of old cards sitting at home that people have sent me over the years (don't ask why). This website is worth a hundred times the weight of that in amusement value. In the unlikely event that you don't find one that you would want to send to someone, they are constantly posting new cards which are guaranteed to make you laugh, unless you are a prick.
Tired of the usual "Happy Birthday" greeting on Facebook? Spice it up with an ecard! It doesn't have to be nice, but that doesn't mean it's not funny! Some Ecards provide satirical ecards for all occasions and you can even make your own.
