American Express Delta Rewards

I am always looking for good coupon codes or ways to save money.  A few weeks ago, my sister told me about the American Express Delta Rewards.  If you have the iPhone app, it's under the tab "Offers Available For You" and when you click on it the page looks like this:

Some of the offers they have available are:
--Spend $25 or more at California Pizza Kitchen and get $10 back
--Spend $250+ on hotel, get $50 back from Travelocity
--Spend $25 or more, get $5 back at Peachy Airport Parking

And get this, it actually works.  So, what you have to do is add the offer to your card.  Then next time you spend the amount at the venue, you get the credit back on your card.  I love my AMEX card!  The insurance policy they have on the card is phenomenon and all the miles we get is just what we need.
