When I set up these clubs as "products" in ShopSite, I assigned $0 price and "No Shipping Charges". When a cusomter checks out, the Checkout page says "No payment information required" due to the $0 total price. Oh oh!

Is there a way to "require" payment information even with a $0 total price? This is critical for club membership sign-ups.
For now, I am forced to apply a $0.01 shipping charge to the order, which looks very unprofessional.
Please help!
