Smart Inception via Amazon offers the Brewooze Keurig Reusable K-Cup 3-Pack with 20 Paper Filters and Water Filter for $7.76 with free shipping. That's tied with our mention from last week and $5 under the lowest total price we could find for this quantity elsewhere. These refillable cups are dishwasher-safe, and are compatible with Keurig 1.0 and 2.0 brewers.
