This is crazy. I use this one so much that I don't even think of it as an app! My Starbucks button!
I've been using this for years now. Mostly to pay for my purchases and get those reward points. Which I save to try one of those fancy girl drinks! Typically I just get a tall coffee in a grande cup (for room to cool down a bit).
Lately I learned that you get a point for each transaction ... not by dollar amount spent. So if I'm getting something more than a cup of coffee to run somewhere else, I buy things separately. First the coffee and find my cozy little spot. Then maybe the newspaper. Or a food item. Or coffee beans. When Mr. Ralph was with me, we each bought our own drink and we each got something free every month or so.
Having the app on my phone makes these freebies easy to remember. Also, I have it set up to automatically reload when my balance goes below $25. The app also has a feature to find the Starbucks closest to you! Which I used last week when I brought GrGeorge a great pumpkin latte (his request).
It probably does way more than this .... try it!
