One of the benefits of a VIP Membership is Skip-the-Month privileges. As long as you sign in and skip by the 5th of the month, you won't be charged for that month. To skip, simply sign in to your account, scroll over the VIP Account tab, click on Account Details (desktop) or My Account (mobile), then click 'Skip the Month' button and follow the instructions. If you don't skip by the 5th, your account will be charged on the 6th; however, there's no obligation to buy. Unspent VIP Credits roll over and accumulate, and do not expire.
When you're ready to pay, make sure to select the Visa Checkout Button
