The sky is really the limit when you consider the prices of various coffee subscriptions. However, ordering your own beans and making the coffee at home will still likely be cheaper than drinking Starbucks every day, and the quality will probably be much higher.
Responsible roasters often look for ways to pay farmers a higher price and still pass on savings to you by avoiding multiple middlemen. By purchasing a subscription from these types of roasters, everyone wins. You pay a fair price for awesome coffee. The farmers get better pay, which can motivate them to learn and grow even better coffee. And the roaster gets a predictable monthly income so they know how to plan their business and continue delivering awesome coffee to you.
