Kids gave me a Keurig almost 3 years ago. Started out using the K-cups. Handy, but expensive. When they gave me the Keurig, they included one of the "baskets" for using regular ground coffee. Now, that's all I use. I buy coffee... DARK roast... and just fill my basket each morning. Certainly, dumping and cleaning the basket takes a couple more minutes than tossing a K-cup. I'll do that for the savings.
This past weekend, our son was home for a few days. Both daughters also spent time with us. With the number of coffee drinkers, I purchased a couple boxes of K-cups for the weekend. Now, back to my basket.
