It's kind of funny how they don't mention the actual rates with the amount of NX purchased. It's not actually 15% for all purchases, which is kind of obvious once you notice how they worded the advertisement.
The actual rates are:
$10 - 5%
$30 - 10%
$100 - 15%
This only seems worth it if you're buying $100 dollars of NX for whatever reason.
