The amount of money you save with resale is fixed, it is the delta between what you paid for the resale contract minus what you would have paid if you bought direct. You will never save any more money than that because the ongoing costs are the same. You may in fact end up paying more over time when you consider being ineligible for discounts such as the Sorcerer pass, etc. Everyone has to do the research and make the best decision for their family.
