Couple yrs. ago I bought a Keurig coffeemaker. Really liked the coffee.
Then got to thinking. My wife and I have a cup in the AM and another in the evening. That’s 4 cups/day.
At .50/ cup it adds up to $60/month for coffee. Took the Keurig back.
She probably spends $15 a day on lunch too.
Brew my own, bag my lunch. Allow for occasional lunches out to celebrate a birthday, etc. Every penny counts.
Personally, I love my Keurig. I found that as a single person living alone and using higher end ground coffee or grinding whole beans; Dunking Donuts or Starbucks or other higher end beans as I prefer using, in my regular coffee maker, I was wasting a lot of coffee, poring a lot down the drain. IMO, it’s hard to brew a decent amount of coffee for only one or two cups without making it too weak or to too strong in most conventional coffee makers. I also like sometimes having just one cup of coffee in the evening so making even a small pot of coffee, I ended up wasting a lot and it ended up being more expensive overall than what I spend on Keurig cups.
On weekends when I drink more or when I have company, I use my coffee maker but for a quick single cup in the morning before I go to work or on those evenings after work when I just want only one cup, I love my Keurig. I also have the Keurig Vue so I can make single serve lattes and tea and iced tea and iced coffee and brew to various sizes and strengths and temperatures. And I buy my Keurig cups via my Amazon Prime account which is somewhat cheaper, with free shipping, than often what I could buy them for at the grocery store.
I bought one of those reusable filters for my Keurig and put my own coffee in. That makes my morning cup better and cheaper than my regular coffee maker. The filter cost about 10 bucks and I have used it for a couple of years now.
