I have a friend who works for a company that refurbishes Apple products. Not all have anything wrong with them. If someone buys one and opens the box and sends it back, it goes thru refurbishment and must be sold as that. Sometime they have a board that has a problem. In other words they are checked out MUCH more carefully than one coming out of a store. I purchased a Mac Air, saved 450.00 refurbished and it is fantastic. I almost prefer to buy refurbished as I know they have been carefully gone over and checked out totally.
