Donate $15 to Greenpeace, get $15 Groupon credit

Groupon is running a cool promotion now through March 31: donate $15 to Greenpeace, and receive $15 in Groupon credit! It's like donating money to charity and getting it all back to spend on yourself. Groupon publishes a deal a day (sometimes more), and your $15 credit can go toward the purchase of another Groupon for a local business. Today's regular deal for Charlotte is for Phat Burrito in South End, but you can save your credit if you want to wait for a different deal. Don't forget to read the fine print, like you need to with any deal-a-day site. I really love Groupon and LivingSocial (the other big daily coupon site), and this is a great way to help a charity and keep your money for yourself at the same time. Click HERE to buy your Groupon.
