I used www.random.org, and from comments 1 through 51, it chose #6:
I'd let Lauren choose what flavor, and I guess that she'll pick blueberry.
I'm thrilled for you Cristi! And for Lauren, too. Trina wants her to know (yes, she just wandered out here again) that Blueberry is her favorite also :) Unfortunately, I don't seem to have an image of the Blueberry flavor, so strawberry will have to do for this post.
There will be another giveaway coming up soon, so stay tuned. Maybe the next one is yours!
Disclosure: Yoplait and MyBlogSpark provided me with the yogurt coupons, the prize pack, information about the new Greek Yogurt, and the giveaway. It was up to me as to whether I wanted to post about this product, and all opinions in this post are mine. I was not given any other compensation for this post.
