$70 is the MSRP for all three versions of Crash Nsane Trilogy from Australian stores. If you found it for less than that was because it's being sold for less than MSRP. The $70 price Activision has chosen to charge in the Switch eShop is just MSRP, it's fair. If you want it for less wait for a sale on the eShop version or buy it at retail where Big W will undoubtedly have it for less.
