Since when has USD5.99 = GBP4.79 = AUD9.95 (the current price for car pack 3)
Today's spot rates show USD5.99 = GBP3.89 = AUD5.76 (no that isn't a typo, Sony has a 72% uplift in currency for Australia)
Lets assume that Sony has a reasonable argument for pricing differently between the US and EU stores (although I can't think of one that would justify such a large disparity) so we just consider GBP4.79 vs. AUD9.95.
Again, today's spot rate shows that GBP4.79 = AUD7.09 (so in this instance, Sony has a 41% uplift in currency)
The AUD has been within 8% of the USD for the last year now, and hasn't had a monthly average above the USD since January 2011, what are you worried about Sony? I'm happy to support your product, but please, stop taking the 🤬
I'm not pointing at you directly, Carlos, but just quoting your post. To utilize some of your information, one thing to consider:
Federal Minimum Wage for each country:
US: USD 7.25
UK: GBP 6.08*
AU: AUD 15.00
*Ages: 21+ (the majority of the age range here)
So let's translate this into USD, since that's what the majority points to:
GBP= approx USD 9.39 (29.5% higher)
AUD= approx USD 15.60 (115% higher)
So using current exchange rates to USD and utilizing the above information for car pack 3:
US: USD 5.99
UK: GBP 4.79= USD 7.40
AU: AUD 9.95= USD 10.35
How many hours would a minimum wage person need to work to pay for this?
US: 49.5 minutes
UK: 47.3 minutes
AU: 39.1 minutes
I have no bias towards this... even though I live in the US. But let's recap:
Joe Smith in AnyState US has to work 10 minutes longer than Joe Smith in AnyTerritory AU. Joe Smythe in AnyTown UK needs to work 8 minutes longer than Joe Smith in AnyTerritory AU. (To compare US/UK is fairly negligible as most of us screw off at work and get paid for it 2 minutes daily

)
I've heard arguments that "my prices are higher for everything else", so I shouldn't have to pay as much. Well, if everything seems to be about the same elevated price... then it makes total sense. Someone described paying twice the price for a measurement of gasoline, and twice the price for DLC. That'd pretty much throw that argument out of the window... you're talking about your country/territory/currency/location, not Sony's price points- they're following suit. Whether this makes it right, is another issue. What's the norm may not be right, but it just... is.
I'd imagine that'd take care of the "why so much more _____(here)?" question.
