They can be any of the above. If it doesn't feel right, don't do it. There are companies out there (ie, Tiger Direct, Newegg, etc.) that will have killer prices on things but they are legit. They will be refurbished but at the same time they are used so they can't be sold at new prices. These same companies can be used from time to time as clearing houses for manufacturers so again, awesome prices. Jim Bob's authorized Apple dealer, not so trustworthy. Trust your gut.
