Problem with that is that there is no real-time inventory checking from mobile app orders against What that particular store actually has in stock at that time. I see several cases a day where people have ordered an item off the app that this particular store doesn't actually have. Not all stores have the full menu. The app doesn't account for that.

I only ordered from the app when Starbucks is running a promo for discounts or bonus stars for items purchased through the app. And I only have the app on an alternate device that has no other data.
