Finished my 3rd month, starting with the 4th. Jake is €2,49 per meal and Joylent is €2,- per meal But it depends how much you buy at the same time.

Also check https://www.blendrunner.com/ as it provides a very nice overview of all the specs in regards to the nutrients and price (also if it ships to US/EU).

I'd be curious about your experience once you've tried a few!
