How to save over $100 each month on Starbucks coffee

I came up with an easy way to save over $100 each month for my favorite coffee drinks and I want to share it with you :)  I love caramel in my coffee and one of my seasonal faves in Starbucks Salted Caramel Mocha or Salted Caramel Mochas.

Heat 1 cup milk. Add your favorite instant coffee(I was on the go so I used a Starbucks VIA packet but any instant coffee will do) Add 1/4 packet (or about 2 Tablespoons)Hot Cocoa Mix. Unwrap a delicious Trader Joe's Fleur De Sel Caramel (or 2 if you want it really caramelly) and place in cup. Carefully pour the hot milk,coffee and cocoa mixture on top of the caramel in the mug.  The heat of the liquid will quickly melt the caramel.  Stir and ENJOY!   Mmmmmmmmmm......
