You can get tea bags for less than a penny per teabag at pound-stretcher. The Typhoo sacks contain around 1100 teabags and are just £9.99. these are the cheapest teabags I've found anywhere, even cheaper than Tesco Value and of a much higher quality. I drink about 6 cups per day so these sacks last me around 6 months each. If anyone can find an even better offer I would love to hear about it.
