We're having some issues with customers picking the 1 cent shipping option, which is ONLY for when you already have a current processing order, and are asking us to combine your orders. (hence not adding a 2nd shipping charge)
This means that the customer has already paid shipping, and wants to put the orders together in one shipment.
What is happening instead though is somehow when customers are checking out they are picking the 1 cent shipping option by default not realizing it isn't a valid option for their order.
Unfortunately this creates an added workload of having to contact customers every day to find out their shipping preference then charge them for the shipping. The time to do this really adds to our already busy day.
We really want to keep offering the combine shipping option, but if this keeps happening we will have to reconsider.
