How Much I've Spent on NX

I've spent $450 at the very most, over the course of 4 years of playing. After the Cash Shop was introduced, I would spend about $23 every three months to renew my NX clothing, pet, and coin magnet (I quit about a year and a half ago). I had once spent $35 or so on Gach and maybe $30 on AP resets. That's about it.
