Does anyone have any advice on how to go about getting the Approach charts for as little $$$ as possible? This topic was just brushed over in our groundschool, so I am trying to figure out what kind of options I have. We have an option to buy the SW set and a 4 month starter subscription w/ the leather binder for $178. Is this a good deal? Can it be beat? If so, where!? Any other ideas on how manage the updating process??
