Cosmo/Identity & Sahra spa discount?

I recall seeing a discount offer somewhere recently that was going to be valid during my trip next month. But of course I can't find it now. Posting here in hopes that someone else remembers seeing it.

I think it was something like $20 or $25 off any service. I found a mention of $25 off specific services here - http://www.cosmopolitanlasvegas.com/pdf/FallTreatment.pdf

Doesn't look like Identity membership @ any level gets you any sort of discount like it does @ Venetian/Palazzo & Canyon Ranch.

Anyone recall seeing something like this recently?
