Look at the sugar. Starbucks drinks are fewer calories in general than Caribou, as well. When I used to drink those drinks a lot and didn't count NI, I preferred Caribou to Starbucks because their drinks were sweeter. When I started counting pts on WW, I saw that the Starbucks specialty drinks were much lower in pts than Caribou's were. In that case, it's because of the sugar. That may be the issue with DD vs Sbux, too.
