Each sachet of P&G™ is provided to global emergency relief organizations or non-governmental organizations at a cost of 3.5 US cents, not including shipping from Pakistan by ocean container. Transport, distribution, education, and community motivation can add significantly to program costs. Sachets are generally sold at product cost recovery for 10 US cents each, for a cost of 1 US cent per liter treated.

10 cents for 10 liters, or a penny a liter. still a lot more than 3.5 cents, but not crazy.

So you're arguing that it costs two bucks to ship it?

Yeah, no.

As the other poster noted, the article explicitly says that the retail price, including shipping, is about 10 cents.

amazon! probably

You could certainly brew your own.

I was referring to the fact that Amazon sellers are charging 50 cents to two dollars (!) for a packet that is sold by the manufacturer for 3.5 cents.
