The Keurig B79 Platinum Plus coffee maker can be purchased online through shopping websites such as QVC as well as through mass retailers such as Amazon. Online auction sites such as eBay also sell various models of Keurig coffee makers, though inventory and selection varies.
Each listing on Amazon features professional photos of the item for sale as well as both a quick summary of pertinent information about the item and a detailed description provided by the manufacturer. Listings also contain comprehensive reviews of the product written by Amazon users. Each review consists of a numerical rating of the customers satisfaction with the product as well as a written review of her experience. Users can rate the helpfulness of each review, which allows Amazon to feature the most helpful positive and negative reviews at the top of the section.
All listings on eBay are created by individual parties and not sourced by manufacturers. As such, it is difficult to predict exactly what items can be found at a given time. However, eBay allows users to create specialized alerts for certain products, or if a new product is listed by a certain seller. This allows the user to act quickly if the item becomes available.
