I received an offer from amex in my email a few days ago. Perhaps it was a targeted offer that isn't as prevalent as I thought. The offer read " As an American Express® Card Member, take $25 off your first purchase* with Google Express and get three months of free delivery** when you make a purchase between now and March 15, 2015 using any American Express® Card. Once your free trial expires, you will be auto-enrolled into paid membership under the payment plan you selected when you signed up. You can cancel at any time."
