These bundled games won't be allowed to be returned, because they are all part of one SKU. That's obviously part of the exclusive deal GAME requested.
The customer cares not about the stores stock reference numbers, and nor should they.
Should any of the items in a bundle be faulty the customer is entitled to return to the store for an exchange, and in the event of the product not being available, a full refund.
I doubt the store will ask for the full bundle to be returned for full price refund, they will just exchange for a different title.
