For the most part I go straight Black Lipton, it’s cheap and gets the job done. But recently I have been playing around with some black flavored teas. My current favorite is a Black Currant Variety. Absolutely delicious.
Also, buying tea from any cafe or restaurant is straight up ridiculous. They charge anywhere from $2-$4 for low quality tea, and you only get a cup. Save your money, brew your own at home, and invest the rest. Think about it, saving a dollar or two a day really ads up, especially if your putting it in an IRA.
