It was always pretty clear that the early costs represented ingredients only, and the ingredients themselves have changed over time. There's also processing, containers, shipping, etc. when you're interested in someone making it for you.

The ingredients list is published and available, there's even a spreadsheet up with online locations where you can buy everything.

I can understand being dissatisfied about cost - but it was never claimed that you could receive this delivered to your door for $100/mo.
