Right now you can get theSolofill Cup, Refillable K-Cup For Keurig Brewers for $11.30. That’s $2.50 lower than the cheapest price I have seen these. If you have a Keurig, there are several reasons to get one of these. One to save money. K-cups are usually around 60¢ each. Two, you get to use the coffee you love and if you grind it fresh it makes it even better. Three, it’s less waste and better for everyone.
