I've been away from here for the past little while, having traded Sydney for a fast paced Hong Konger's life (thank god for university breaks) and shopping to my heart's content. Back now and I must introduce everyone to one of my favorite shops- Cher2, a discount nail polish retailer (did a google search a while ago and couldn't believe the lack of results that came back). The range is amazing and bargain hunting (OPI for less than 10AUD!) could just be my middle name, so what not to love?
Look at the website for the store list- it might involve navigating dark old elevators but the result is well worth it.
