Basically, this allows you to save some money when buying your fishing license. That's because every time you buy a fishing license in PA, you pay an electronic processing fee & an issuing agent fee. While these fees aren't much, the do add up over the years. Buying a license that's good for a few years will mean that you won't have to pay the extra fees for the extra years the license is good for. Plus, you won't have to worry about getting a new license every year. This is especially helpful for the folks who fish every year in PA, but live out of state. Normally, your first stop when taking a trip in PA would be to an issuing agent to buy a license every year.
Do check the new prices for these multi-year licenses. If your an angler who doesn't fish in PA very often, then it's probably not worth the extra money. However, for those of us who fish a lot in the Keystone state, then it could be really convenient. You can see the prices for these new multi-year licenses HERE. If you have any questions about fishing licenses in general, the Fish & Boat Commission have a webpage of answers to all your questions HERE.
Also on December 1st, the Commission will be raffling off different fishing trips to various locations. It sounds like a good opportunity to win a nice fishing trip to one of PA's more famous fishing locations. You can learn more about these trips HERE.
