Coffee drinkers aren't giving up their fix, but some say they're choosing from several brands based on price. Coffee bean prices jumped 77% last year and continue to rise even faster than gas prices. J.M. Smucker this week said it was raising prices an average of 11% on its packaged Dunkin' Donuts, Folgers and Millstone coffees, the third increase since last summer. Kraft, Peet's and Green Mountain also have raised prices recently.
