I buy pods from Costco for about a quarter each.
Since I average about one cup a day, it’s an easy way to go.
My Keurig broke and they sent me a new on on warranty but didn’t want the failed one back.
I took it apart, there’s a LOT of parts in there.
I drink A LOT of coffee daily, packing my own reusable pods is the cheapest route I can go and I can make coffee to my taste.
I actually like my Keurig, though when it breaks (and it will) I still have my trust ol' Mr. Coffee and a pack of filters for that on standby.
