Get a free rewards card for free shots, syrups and cream. Then if say you want a gingerbread latte, order a normal latte and add the syrup and whipcream and you get the same thing for cheaper...
Try a caramelmisto. Just like a caramel latte but made with brewed coffee instead of espresso shots - very similar taste but less cost & fewer calories. The Venti w/ skim milk is only 90 cals!!!!
