This weekend, treat yourself to a nummy Wendy's Frosty, and 50 cents of the purchase price will go toward helping increase foster care adoptions. Pretty much a win-win situation. I can't see a downside at all. I will personally be eating Frosties all weekend. :)
Also, go to FrostyCard.com and create a freee-card to send to your dad on Father's Day and Wendy's will donate 25 cents. Pretty cool.
