Hey Ryan,

I know this one has been on the to-do list for awhile, but I would like to once again voice support for a way to handle check out if the customer's balance is $0 (such as if they used a coupon or "bought" a free product).

Many of the websites I work with use free giveaways or "loss leader" products to draw in potential customers (who they can then market to later). With the ability to change a user's role upon purchase now in Ubercart core, this feature is especially needed so that a store can offer something like a free "7 day trial membership" (which upgrades a user's role for a short amount of time).

I'm hoping this can make the beta cycle. I view being able to accept a $0 balance total (without requiring a credit card number) as quite important.

Thanks,
Ben
