Sync Your Amex Card with Twittter & Save $20 off Your Purchase $75 or More at Whole Foods
I synced my Amex card with Twitter and tweeted the offer shown on their Twitter Page. Yesterday, I purchased $105 in groceries and got a $20 credit on my card account. Once the offer is redeemed, you receive an email stating that you got the credit. Very easy and no printables involved.
