It's on iOS.Is this on android? That's another thing the rep said wouldn't happen, in most cases anyway. I guess this would be bad if you use a google play card ($50) and think you're covered, but then you have to pay extra tax.
I hope a weird number like $53.54 means tax is already included...
It probably sounds like that's with taxes included, although I never see them listed in the price. It's always added after the purchase.
