Well, I have 6.09 balance and I want to get Heavy Mach (0,99) but I also want enough money left to be able to either purchase Zen Bound or Sway (depending which one is better for me) and they are 4.99 each. So without tax it would be 4.99 + 0.99 = 5.98, leaving me with 11 cents. But I have heard some people have to pay tax. I've been looking at my receipts Apple has emailed me, it looks like I have yet to pay tax for any of the games I bought. Anyone can clarify?
