Vacuum-sealed coffee does not equal fresh coffee. When coffee is roasted, it releases carbon dioxide and continues to release it for days afterward. Fresh-roasted coffee can be packaged in valve-sealed bags to allow the gasses to escape and will taste best about 48 hours after roasting. To be vacuum sealed, the coffee has to first release all its CO2 or it will burst the bag. The vacuum bag will indeed help preserve coffee longer while it ships and maybe sits on a store shelf, but before it shipped it had to sit around for a while before it was "sealed for freshness." Vacuum sealing is best for pre-ground coffee, which we already know is not going to taste as good as fresh-ground coffee.
