Harmony test and gender

Ok my insurance does not cover this test because it's not medically necessary.  I'm not going to lie I want it for the gender. We have 2 girls and this is my last pregnancy and hoping for a boy! Now I have done research on line and red it can be expensive. I called and spoke to a representative at diagnostics where I will be getting it done and they told me I would be billed $130 total for the whole test. Anyone recently looked into this?!
