I have had this blush for a while now, I purchased it at my local CVS store for $8.99 (direct link to product.)
If you want to check out the haul where I talked about this product it is here: Collective Makeup Haul: June.
Both blushes are very good. But if you want a cheap dupe for the Nars $29 blush, go for Luminoso (which is less than $10!)
I would recommend this product to people with light to medium skin tones who want a peachy, dewy finish on the cheeks.
