I got ridiculously overcharged!!!

I bought the 99cent dragon stone, and I look at my bank account and I got charged $13.74, that is ridiculous and uncalled for, I get that theres going to be online tax but, this is ridiculous, there is no reason I shouldve been charged so much for something so cheap, you need to check your games purchasing system and make sure it isnt gonna be doing this to other people cause this is ridiculous
