I am kicking myself over and over again for not buying at least one backup of MAC's Viva Glam Cyndi lipstick. The coral red shade is a lustre finish which normally applies a bit sheer, but this shade packs lot of shine and color on the lips. I love it for day or night
but tend to only use it sparingly because I love it so much.
One day I decided to search possible dupes and stumbled upon a couple of posts that said Wet n Wild's Natural Blend Lip Shimmer in Spice #106 is a close contender. After searching my local CVS, Walgreens, and Wal Mart, I finally found it at the latter.
Here are closeups of the two products. Viva Glam Cyndi is discontinued but sold for either $14.50 or $15.00 (however much MAC lipsticks were running or run these days) and the Wet n Wild was around $1.99-$3.00 (I can't remember the exact price).
