Flubit
Flubit is an online shopping service that generates competitive offers based on interest in a designated product. Users receive offers by submitting a URL from a compatible online marketplace into the site's "demand engine", which compiles offers from varying retailers. Users are then alerted to discounted prices for the product they showed interest in and have the option to purchase the product at that price or decline the offer. Shoppers save 10% on average for products.
The service claims to "disrupt" rather than compete with major retailing giants such as Amazon and eBay by diverting online shoppers from well established marketplaces to instead make purchases directly from smaller retailers.
