K-Cups are wasteful, but at least they ship three months (90 K-Cups) at a time and there is very little wasted space during shipping (it is just packed coffee). Is it a waste of plastic/foil? Absolutely. But in terms of shipping waste, K-Cups aren't near the worst.
These on the other hand are shipping around tap water. That uses up fuel, it uses up space, and it arguably wastes even more plastic. There's no reason this couldn't be shipped as a powder and sell you months and months of the stuff.
The saddest part is that they USED to sell the product like that. They're moving to this method to increase the price (and let's not pretend: It is a marked increase).
