I came here before reading other Yelpers' reviews, and I see what they mean when they say that the service isn't the best. However, I walked in with the intention of browsing on my own and I was able to do so. I don't know about the other products, but the nail polish here is a lot cheaper than other places and there's a pretty decent collection.
I was able to purchase China Glaze Magnetix for $6.49 (other places sell for $10-12+). At the counter, there's a basket of clearance polishes and I grabbed two Essie polishes from another season's collection for $3.99 each. All other China Glaze nail polishes were also $6.49 and Essie for $6.95, I believe.
For these prices, the polishes are the cheapest I have ever seen.
