This tea is very good.  I discovered it while visiting in California. The moment I got home I searched local stores for it and I was not able to find it.  Finally I decided to see if Amazon had it and they did and I bought two boxes.  As long as they make it I will buy it.

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
