I originally built this for myself to keep track of good deals on an iPhone 6, but since then hundreds of people have hopped on board, and I love getting emails/tweets about the awesome deals they're getting with it. Someone managed to find a rare electric/acoustic guitar hybrid at the price they wanted, how cool is that! Denarri gets you from search to buy in 3 clicks, and it does this in 3 ways: It learns your search preferences, simply type in what you're looking for, and it'll already know the price range, location, condition, etc. you had in mind. You can of course edit these prefs whenever you want. The MatchCenter hand picks the best matches for all the items you're following. Fire up the app, and you're always seeing the most up to date results, no need to repeat the same searches over and over, or sift through tons of knockoff/scammy results. The notifications are based on priority level. Need the item soon? It'll give preference to closer sellers, and notify you more frequently of new matches. Not in a rush? You'll get periodic updates, so you don?t miss out on deals, but don?t get swamped with notifications. I want to make this the best shopping app out there for you guys, and have many great features in the pipeline (like searching ebay and amazon simultaneously, and selling through the app for free!) and I want to know what you want added/changed to make it even better. Looking forward to hearing your suggestions You can find the app in the iOS app store by searching "Denarri", and you can head over to denarri dot com to learn more. I would've put the links in, but I'm a new member here so I'm not able to yet. Make sure to use the promo code BLACKHAT and you?ll be entered to win a Nexus 7 tablet, and get 6 months of fee-free selling.
