I love our Keurig. I bought three when Sam's Club had a special buy on them three years ago. I gave each of my DDs one. All three are still working great. They have a filter that has to be changed about every three months. I buy those at Walmart six filters in a package. I buy the K cups at Sams' Club in the case for DH's brand of coffee. I buy from Brad's Deals when the K Kups are on special buy one box get one free and free shipping up to 8 boxes at a time. Lots of special buys fro K Kups listed all the time from coffee manufacturers, even Starbucks that my girls like. I never buy the box of cups at the grocery store. Way over priced compared to the online sales.
