Get thee to Walgreens and look for the Sinful Colors St. Patrick's Day display! The display has repromotes of various polishes, and four bottles of the new glitter top coat Shamrockin'. I haven't even tried it yet, just grabbed it and brought it home and took some bottle shots.
Shamrockin' has small green glitters, medium yellow glitters and large white flowers. Granted the white flowers have turned up in a lot of glitter top coats in the last year, but it's cool to see them in a drugstore brand AND used so well for a themed polish.
A word of warning--there were only four bottles of this in my local Walgreens, and the unique polishes go first and fast, so if you want it, get it STAT.
