I'm Australia and the prices for gems on iOS went up a while ago. A 580 gem package at full price is $129.99 AUD, and $89.99 at 30% off, or 31% to be exact. For some reason Android was cheaper for a while, but I noticed that the prices are the same now no matter which platform you play on. I used to buy my gems from Android due to it being cheaper but I see TL have changed that little loophole since its been mentioned here in the forum about the discrepancy in pricing.
