NEW YORK ( TheStreet) -- Coffee chain Starbucks ( SBUX) has been adjusting its prices in several markets for about a year since it switched to a different pricing model. Prices in the Northeast and Sunbelt areas were raised recently about 1% on average, according to Starbucks spokesman Jim Olson. He added that the price of the grande-size brewed coffee, which is Starbucks' most popular drink, hasn't been changed in any market. The "dynamic" pricing model Starbucks uses takes into account products' relationships to each other and customers' purchasing habits, explained Piper Jaffray analyst Nicole Miller Regan.
