Like

 

Like gets people's opinion into the product.There is a dialog between the clients where each product can contain feedback from them. So next time you go to the supermarket you can choose the best products.

 

The main goal is to give the user the chance to choose whats really good and not only depend on good/bad publicity.

 

Other two important benefits are for the supermarket, which know what client like and can organize/optimize the spaces; and last and an important outcome will be that the producers have to make good products with the user as center and not only relaying in their reputation.
