What kind of extra profits do you think Coke brings in from the excess consumption from religious rituals of Spiritual Healers?
Lets say Chiapas (3.4 million people) has (10% population of Spiritual Healers) = 340,000 Spiritual Leaders.
Each spiritual leader will now purchase a 1 Liter coke for a religious ceremony EVERY DAY that they otherwise would not have. Coke costs .73 pesos per liter in Chiapas. 340,000 x .73 Pesos = 248,200 Pesos per day.
248,200 Pesos coverts to $13,992.88 USD per day.
$13,992.88 x 365 (days in a year) = $5,107,401.20 USD Total extra coke consumption.
So Coke is now possibly selling 5 million USD more dollars per year of coke with this scheme. You must subtract the cost of making coke which we do not know, and the cost of the "bribes", to find Coke's total profit here.
But as someone involved in marketing the potential downside of this scandal doesn't seem worth the extra 5 million in sales from Coke used during religious rituals in Chiapas.
It seems more likely to me that if mothers are feeding their babies Coke instead of the expensive milk, or contaminated water, that the Spiritual Healers are making the same decision as everyone else. That Coke is the safest, most cost effective and pleasant drink available.
