Oh wow, I have spent way too much time on the someecard site this last week.
Their motto is "when you care enough to hit send". They are so much better than the other ecard sites out there, especially if you have a warped sense of humor (which I do). I find almost everything on it hysterical. And, best of all, they're free.
So, since I don't have the email addresses of all my readers (and it'd probably end up in your spam folder anyway), I'd like to wish you all a happy Earth Day.
PS- Dig This Chick, I think you'd especially like this one.
