Our software is smart enough to know what you have purchased and what you are upgrading to.
For example if you have bought the skipper course for $67.50 and now you want to upgrade to the Skipper bundle (normally $95) you will only be charged $33 for the upgrade.
Skipper = $67.50 on its own
Maneuvering Under Power = $39 on its own
Bundled price $95
