Special "point" Cards!

Most stores I've been too have special cards that you can get (they are free) that give you special rewards when you buy from that store! Every time you buy something (depending on how much it costs) points will be added to your card. Once you have enough points, you can get free stuff, or discounts! I know Sephora has one, and so does American Eagle. If you sign up for the emails, you will usually get a special birthday discount, of free gift! They are a genious idea and its really fun when you get a special discount!
