Clean, simplistic, easy to use eCommerce website with enhanced social networking functionality

An eCommerce website with a simplistic, easy to navigate design. The website would also need to require accounts to be made for each user. This website would need to hook into the sharing functions of all major social networks (Twitter, Facebook, Google+, Tumblr, etc.). In addition to this it would also need to hook into other websites such as [login to view URL], [login to view URL], [login to view URL], [login to view URL], etc. to find whatever it is that the user is looking for in each store by simultaneously looking for items in those respective stores, and then displaying a link to the website with the lowest price for said item, or related items if the specific item can't be found. In addition to this, the website must also compare the online prices for whatever item the user is looking for against prices for that item that could possibly be at stores that are near the user locally. If a local store had the lowest price, the user would be presented with driving directions to that store, a phone number, and the name of that store. There would also need to buttons to allowing sharing of that link (along with the price of the item that is being shared) to the social networks that are listed above, allowing the customer to share what they just bought or found online, with their friends.
