So just out of curiosity I did a price by volume comparison. Tom Ford nail polish is .41 ounces for $32. The standard line of GA nail polish is .2 ounces for $20. That values Tom Ford NP at roughly $78/oz and GA nail polish at $100/oz. So already, GA is priced quite a bit above TF which I would consider a comparable luxury line.
Now the runway NP is priced at $30, so that would make it
$150/oz!
So, one more comparison with the highest end NP I'm familiar with: Christian Louboutin nail polish is .4 oz for $50, so that makes it $125/oz. So Armani has even outdone Louboutin with this price tag!
EDIT: In fairness I just wanted to add that, while I don't have many GA NPs, the ones I have are fantastic and I think being on par with TF or, at most, in between TF and Louboutin would be reasonable. But with Louboutin you also get
that bottle! So I think to price themselves above Louboutin is just unreasonable. But my complaint has nothing to do with the product because I think their NPs are superb.
