We're using Ubercart 5.x-1.7 for the development of a site. We have a few sample products in our catalog that have a cost of $0.00 (free). The customer is also not charged any shipping and handling for these items.
Is there a way to use the Ubercart to have customers place orders with these products? Right now, if I add a $0.00 cost item into the shopping cart, and click "Checkout", the module does not let me proceed.
Maybe there is a coding workaround for this? Obviously we could just put all of our sample products on a separate Drupal page, and allow people to send an email requesting samples. However it would be very advantageous if we could just make it part of the regular ordering process. Customers could just add sample items to their shopping cart as part of a single order.
