I also got hit with the tax (Utah)
The thing that really
annoys is that I thought Blizzard had screwed up my billing. I was thinking "hey, this game was supposed to cost $14.99 a month, those liars charged my credit card for more!" etc. etc. Just as I was about to fly off the handle and make the phone call, I remembered something vague about "some
people might have to pay taxes on this" and I thought "Gee, I wonder if that might be me."
Admittedly, it is not that big of an amount. However, it's the principal of the thing that bothers me. Blizzard could've softened the blow a little bit, too, by just:
1) Letting me know before hand that I was going to be one of the ones it effected
(this would be good customer service) and
2) Putting the tax amount as a separate value, labeled "tax" on the billing page. Currently, it just says that I'm going to be charged another $14.99 in a month, and that is manifestly untrue -- they need to put down that they
are charging me $14.99, and the government is charging me the rest. It isn't that
hard to code a feature like this.
