Starbucks announced a price increase that goes into effect Tuesday, June 25, 2013. The increase will amount to 1% overall, but not on all products.
What will change:
Small brewed coffee will increase by 10 cents, and other drinks could increase more than that. The increases will vary by region and may apply to different drinks. That could wipe out the 10 cent savings you get with a reusable cup.
What won't change:
Medium and large brewed coffees and Frappuccinos won't change in most of the 11,000 U.S. cafes.
Here is a nice map of which U.S. states have the most number of Starbucks per capita - http://en.ilovecoffee.jp/posts/view/18
