Mac Sold me a Retuned Device:
My Mac ended up being a return item that was never changed in Apple's database. They saw that on record, and made the change. The Mac was a failed device after plugging in a gaming keyboard, and it never powered on.
Point being: Make sure this is not a returned item. How to do that would depend on the retailer. So, ask a store manger, if they can assist you with a transaction research.
