Walmart offers the Proctor Silex FlexBrew Single-Serve Coffeemaker in Black or Red for $16.88. Opt for in-store pickup to avoid the $5.99 shipping charge. That's $2 below our May mention, the best deal now by $13, and the lowest price we've seen. It features a 10-oz. capacity and can use any single-serve K-Cup packs or any ground coffee.
