Walmart offers the Ninja Coffeemaker System in Black for $64.57 with free shipping. (VMInnovations via Google Express has it for slightly less.) That's tied with our January mention and the lowest price we could find by $3. It allows you to brew a cup, travel mug, half carafe, or full carafe in your choice of classic, rich, or over ice.
Considering making improvements? These are the changes least likely to help close a home sale.
