As of March 22 there are approximately 88 available colors for sale from Julep. Each polish retails on their website for $14 and weigh 0.27 fl oz. They also have a subscription service for $19.99 a month (plus applicable tax) where you will be sent one of five style boxes. Each box may contain two to four polishes, depending on the month and box.
They also have monthly Golden Boxes were random subscribers will get a box filled with extra goodies and they also have Mystery Boxes for $19.99 filled with items worth $60 to $200 worth of Julep products. There are special promo codes for new members where the first box can be purchased for as little as a penny and up to $5 depending on the promo code. I'll have information on those promo codes up on my blog as I find out about them.
Also they have a referral system - every two people you refer and who sign up via your link will earn you one free month!
