The personalization system learns your preferences as you use it, so you never have to repeat yourself. Search for your favorite electronics, and it'll automatically know the price range, favorite brands, and item condition you have in mind.
Denarri acts as a personal shopper, keeping a lookout behind the scenes, and notifying you when new matches are found according to how high priority the item is to you. You never get unwanted notifications, and never miss a deal.
The MatchCenter intelligently eliminates the noise and shows you only the best and most up to date matches, so you don't get overwhelmed with thousands of results, or have to make the same search every day. All the items you're following in one place.
