In both physical & digital copies of video games: when I’ve visited an store, upon looking at the price tag (they range at 90 AUD or more for a copy, seriously?!) I’ve also browsed through their Steam store front which isn’t any better, 110-30 AUD for a digital license?! When you consider regional pricing, they end up costing more than USD (depends, like a +20% increase which is insane to me). To put it into perspective, games are cheaper in my country than they are in Australia.
As SaveTheTuaHawk said add gst
But also whilst the conversion rate on XE might be less you can’t convert currency at that price, once you add in conversion fees that will also increase the price.
