Facebook page - best way to offer coupon?

[irideflatland]

Just made a facebook page for our e-commerce store. I want to run a Facebook ad that says "Like us and get a $5 coupon".
How should I do this though? If I post the coupon on our page, then anyone who looks at the page can see it even if they don't "like" us.

Can I add a coupon tab or something? I'm completely new to facebook pages so I'm not sure what I should do here.

No, but there is a way you can make people who haven't "liked" your page see something different than people who have.
