How does the FabKids VIP membership work?

FabKids VIP Membership Program:

When you make a purchase, you have the option to enroll in our flexible VIP Membership program. As a VIP (Very-Impressive-Parent) Member, you'll receive exclusive perks, discounts, and special VIP pricing with head-to-toe outfits starting at just $29.95, and individual styles starting at $14.95 (that’s a savings of up to 40% off, Yay!). The choice to shop is always yours. Simply visit your FabShop between the 1st and the 5th of each month. If you don’t make a purchase or skip the month by the 5th, you will be charged $39.95 for a member credit on the 6th, until you cancel. Each member credit can be redeemed towards any purchase of $39.95 or more (including outfits, styles, or both). And it never expires, so you can use it to shop at your convenience.
