Read the Terms and Conditions that you have to check 'I Agree' for before you can purchase anything from this site. It TELLS you about the VIP membership that you're signing up for (I do agree that it should have been an OPTION to join, whereas it literally gave me no choice) but it DID TELL ME that that's what was going on and exactly what a membership entails. Including the monthly charge if you don't make a purchase (can't remember if it stated a specific total price amount, or if any little thing would be acceptable), or if you don't 'skip a month'on your profile page.
I have ordered two pairs of shoes from this site and they are absolutely fabulous. Both arrived within a week of the purchase date and I was able to track my packages for the entirety of the delivery. I love my new shoes and will be buying from JustFab again in the future.
