Amazon offers the Lipton Black Tea 48-Count Box 12-Pack (576 bags total) for $18.41. Add it to your cart via Subscribe & Save to cut it to $15.65 and bag free shipping. That's $0.03 per tea bag and $14 below the lowest total price we could find for this quantity elsewhere. (For further comparison, we saw 312 Lipton tea bags for $8 with free shipping five weeks ago, since expired.)

Of note, be sure to cancel Subscribe & Save after your order arrives to avoid being billed for subsequent shipments.
