I had a favorite saved for an online retailer of OPI and Essie polish at really great prices. I can't find the favorite!!!! All I remember is there was the number 8 in the name of the store.
I buy them from Avenue You Beauty... They charge full retail prices, but UPS shipping is only $1, they get the stuff out fast AND they're only ~1hr away from me, so I always get my order within 2 days
