It's too expensive.

I drink lemon-ginger tea almost every night because it's the only thing I swear by to ward off colds, coughs and fevers.

I bought the Twinings brand when Superstore was (I'm guessing) waiting for new stock to come in because most shelves were almost empty. I've tried almost every brand and PC is 10/10 for me. Twinings does not steep as well, and the price was almost double.
