In 2010 SodaStream launched an international campaign to raise awareness of bottle and can consumption. The campaign involves the display of 9-cubic-metre cages in various countries, each containing 10,657 empty bottles and cans. Begun in Belgium, the Cage campaign has since visited 30 countries with the message that the waste produced by one family over the course of five years from beverage containers – 10,657 bottles and cans – can be replaced by a single SodaStream bottle. When a cage went on display in Johannesburg , South Africa in 2012, Coca-Cola demanded that SodaStream remove its products from the cages and threatened to sue SodaStream. SodaStream responded by dismissing the threats and announcing that it would display the cage outside Coca-Cola's headquarters in Atlanta .    
Before placing an order, you might want to know what it will cost to go this route. Typical prices for concentrate are $8 to $14 per quart, $7 to $10 for pints, and $3 to $4 for 4-ounce bottles. Shipping will be expensive—count on an additional 30% to 70%, depending on how much you order and the distance. Depending on these factors, flavoring costs are likely to range from $ to $ per liter. Obviously, at the high end you won't be saving much if any money over SodaStream's flavors, once you add in the cost of sweetener; but if you can buy a few pints or quarts at a time, the total cost (concentrate plus sweetener) will fall in the $-$ range. Most or all of the ingredients will also travel less than the SodaStream bottles, and what does travel will mass less, which all adds up to being better for the environment.
