Philadelphia's tax will be levied on distributors. Only time will tell how much will trickle down to consumers. The tax could add up to 18 cents to the cost of a 12-ounce can, $1 to the cost of a 2-liter container, and $2.16 to the cost of a 12-pack. It will affect sodas, teas, sports drinks, flavored waters, bottled coffees, energy drinks, and other products.
