As a coffee addict who buy a gazillion Starbucks Frappuccinos and Doubleshot energy drinks every year, I probably spend at least $5 on bottled/can coffee every day. That works out to about $5×300=$1500 a year if I miss couple days.
Well, you can brew your own Starbucks coffee and make your own Starbucks Frappucino with the old Frappucino you’ve collected. Not only will this be fresher bottle of coffee, you can customize your coffee by doing things like substituting honey for sugar or even not adding any sugar/honey.
Whatever the case, I gotta start doing this more often so I can save money and also cut down on my own glass waste.
See full instructions for this here although I am sure you can figure it out yourself.
