Purchase $50 gift card, use 19.99, remain 18.37
I recently purchased a gift card costed $50 to buy in app product. It then charged me 58.22% tax for a purchase that just 19.99. As the result, my remaining balance is 18.37. I need answer to this question: Why do I have to pay that much. My location is Texas, US. Thank you for your supportive answers.
