Right now on Facebook, you're able to tag your friends in pictures and tag your friends in notes that you want to share with them. So, we're looking into a way of playing with the Facebook tag function to help friends tag each other in deals and coupons that they like.

By tagging your friends in deals, users can spread the word of great sales to their friends who they think may also be interested. This gets the word out of great sales quickly to you and your friends so you can take advantage of them before they're gone.
Our tag function would let your friends tag you, and then you can tag your own friends to spread the word even more. Everybody can use a seat sale right? Heck, if 10 people each tell 10 people who each tell 10 people, the deal has already been told to 1000 people. And sometimes on Facebook, this process can happen in minutes.
For bargain shopping, this is what it's all about - to help consumers save money, while getting consumers talking and creating a buzz about businesses and products.
Screenshots coming soon. Stay tuned...
