Editing a price in a sales order - does not work for client having a pricing rule

I learned that there are times that I need to edit a price for a variety of reasons.

But, I also figured out that when a client has a pricing rule, the edited change does not stay, where as a client with no pricing rules, they can be changed with no issues.

A current example is I need to make one of the items free for this order.
I change the price to $0. But, it iwll not save.

How can I edit a price in this situation?

Thanks

Any ideas? It seems funny that one can edit a price, but because there is a pricing rule, no editing is allowed.

Help! :slight_smile:
