Gap stores on Friday will tempt shoppers with free pairs of jeans. The catch? You must check into a Gap store using Facebook Places.
The national promotion includes 10,000 pairs of free jeans and all Gap stores are participating, according to the deal's Facebook event page.
To be eligible, go to a Gap store and check in using Facebook Places. Then, show a Gap employee your check-in.
Facebook Places is a service that lets users broadcast their location to the rest of the world via devices like iPhones. Offers like the Gap promotion mark an attempt to generate more users by tying "checking in" to retail deals.
If you're too late for the free jeans, Gap will still give you 40 percent off.
Weigh in: Does the offer make you more willing to use Facebook Places?
