Zero Dollar Checkout should NOT go to Paypal

Hey, I know there’s no Free level in ProSites, but, during testing of the ordering process, I want to create free accounts, including with a 100% off coupon code.

Unfortunately, the checkout still directs to Paypal, and there are problems on the return (to the same page), none of which matters, if the logic were fixed.

Can we get this simple fix made, please, or a pointer to where to fix it in the code?
