I failed to notice because the pricechange didn’t affect grande or venti (medium and large) brewed coffeesand I don’t mess with smaller sizes, but anyone who purchases tall size(small) brews saw as much as a 10 cent increase. The company’s thirdquarter revenue rose 25% to $417.8 million from $333.1 million a yearearlier, and green coffee prices have plummeted, so what gives?Starbucks claims the price increase is due to rising labor and non-coffeecommodity costs, but with the significantly lower coffee costs alreadyimproving their profit margins, it seems unlikely this justification is the truereason for the hike in prices.
