How to create Ubercart recurring order with initial $0.00 charge Is there any way to configure (or trick) Ubercart (7.x-3.4) into accepting an order with initial 0 charge, then subsequently charge non-zero amount?

Goal is to offer a promotion with $0.00 initial charge, then start charging after n-number months or days. 

When 0 is set as the cost of the recurring product, Ubercart responds with an erroneous error about no payment method being set up.
If you look at ubercart subscription it offers the ability to create a subscription product with an initial trial period of x days/months and then the amount to charge per day/month following the trial period.
