Sometimes you just need to change the line items on an order- increase a discount, reduce a shipping cost, or whatever, to keep a client happy.
You may or may not be able to do this with Edit Orders, but even if you can, this mod removes and replaces the records in the
orders_products table, which may not be desirable (if you have additional fields in that table which are set using custom logic, as is the case for dropshippers).
Now you have a new option: Zen Cart Order Total Edit. Hope it helps your business!
