As you have explained it’s Apple not yourselves adjusting prices.
I have raised this issue before and to be honest think it’s unbelievable that people round the world pay different prices for the same in game item.
10000 gems in the US cost $99.99
Same in the U.K. cost £99.99 = $133.60
So not only are the UK paying $33 more now! We also get the pleasure of a 10% rise in the new year. So we are going to be paying 40% more for gems.
I cannot purchase more items knowing I am getting shafted.
