If you're living, or have a relative living in Southern California, get ready. My big sister lives there and recently hit the polish jackpot. She cleverly Google, Binged and Yelped until she found a few stores selling some of our favorite polishes for dirt cheap. We're talking $2.50 for China Glaze and $5 for OPI.
I've updated my Where to Buy Polishes page with all the info, so take note, and bathe in the glory that is supply stores!
