My approach isn’t the only one but it definitely creates a lot less waste and saves money (for everyone involved) in the long run. Using your own coffee mug, or mugs, means there’s an upfront cost for one cup, one time. Using a French press means you buy it once unless you break it. Then you just buy one grinder to grind. All of that will cost you less than the cost of a single Keurig machine up front, so I don’t really see how that’s saving money at all. A $80 single use machine costs $50 more (without shipping) than everything I listed that I actually bought. Then add in the K-cup cost since it’s a per use expense, and you’re spending more money every cup.

So, for about $110 upfront, you’re proposing it saves money but I’m just not seeing how you’re saving anything at all. All of my costs, including shipping, are less than $55, which is $35 less than the cheapest Keurig costs at Amazon (from Amazon, of course). When you factor in shipping for the Keurig and then the K-cups, you’re either pushing $100 or over it.

How does that actually save money? All it does, truthfully, is save a few minutes and creates an exponential greater amount of disposable waste.
