Buying in bulk is the way to do it. Keep in mind that hops are harvested once a year and packaged. When you buy bulk you know how they were stored, because you stored them. When next June rolls around and people insist on buying ounces because they are the freshest have no idea how they were stored the last 8 months or so. If you kept yours in the freezer in barrier bags / vacuum sealed mason jars, you will have fresher hops. I've purchased year old hops that were properly stored and had great success with them. Even after I had them a year myself. Which made them 2 years old.
