Today Starbucks announced a mobile app for Blackberry and iPhone that will let customers pay for the coffee. That's wonderful and very convenient for Starbucks coffee drinkers.
Just one more thing they should really do is - add Free drink on mobile app, too!
I am Starbucks gold card holder myself. And, after every 13 drinks Starbucks gold card holders get a card in the mail for a FREE drink. Its kind of a hassle to keep those cards, not lose them and use those before the expiry date. Earlier it used to be a free drink right at the time of card swipe.. but later Starbucks changed it.
I think it would really help to go mobile if the FREE drink is added on the mobile app.. in fact, a little count for remaining drinks for the FREE one would actually increase Starbucks sales!
