When Starbucks competes with itself
At my local QFC supermarket there's a Starbucks counter just inside the entrance. They sell coffee beans for $10.49 a pound, in bags of a pound, pre-measured and sealed.
In the coffee aisle of that same QFC, they sell Starbucks coffee beans in sealed bags for $11.99 for 12 ounces. That works out to about $16 a pound for the same beans, with less variety.
I think it's a bad sign when Starbucks is competing on price against its own landlord -- and winning.
