Boost a friend with the Diet Coke application on Facebook, and they’ll receive a printable $1/1 Diet Coke coupon. Make sure to ask them to “boost” you back so you can score one too.
This is valid on the 14-20 oz. size which often goes on sale for $1, so watch and wait to score your FREE Diet Coke!

I don’t get it…. I sent one to my sister and she sent me one back, but neither of us got coupons. We did the “send boost” but it just posted a picture of a diet coke on our walls… more like what I’d think “send a virtual coke” would do. How in the world do I get the coupon?
