Starbucks coffee info help!?

So im trying to get a gift for a coffee fanatic and they looove starbucks. Im trying to find if they order like more espressos or coffee from starbucks...but either way does starbucks sell the ingredients to make certain beverages. Like they have a single beverage machine called the Barista Aroma...if this persons fav. drink is a coffee with all that cream and caramel and whatever else...can i order that stuff off of starbucks website? Like maybe get the machine then get a months supply of that particular beverage so they can make at home...I was on starbucks website and they offered no clue to how their online gear and whatever works...if anyone knows any info that would be awesome...thanks!
