> You could just as easily say that sparkling water is a mistake when you can get tap water and seltzer tablets for cheaper, or that Coca Cola is a mistake when you can get sugar and caramel and water and mix them yourself.

Not sure how you will get the coca / kola[0] taste in there though.

Edit: fixed cocoa to coca/kola.
