One product, multiple sellers In a multiseller Drupal Commerce Installation, where every Drupal user being a seller,  Some products can be the same from all users, for example a book from some publisher which can be sold by many sellers. Like in amazon, if one is searching for a book, it comes up and shows other sellers also of that particular book.

Is there a way in Drupal commerce to achieve the same?
Sure! I would recommend you:


Create a taxonomy called "global_sku" ... Amazon calls their psuedo sku "ASIN" ... which is just a number that ties all the "product displays" to one page. 
Now ... on your product displays, you could create a taxonomy reference to global_sku's 
And then add some Views that will bring in related products based on the taxonomy.
