I use real time shipping, but NEED to trigger free shipping on ORDER when item is too large for UPS
I use real time shipping through UPS for shipping products with weight. BUT, when someone orders a specific product, that will be common for a lot of items, I want the entire order to be free or flat rate shipping if possible (in this case no charge for shipping where I can build in a flat rate in addition to the purchase of a product).
Here is my real world scenario; I sell industrial sewing machines. The machine head and parts, accessories can be shipped via UPS. BUT, if the customer orders a power stand, or large cabinet, the order and all items then are to be shipped via commercial van line, no UPS charges at all for anything.
I have have checked the product bundles,and any other product shipment types, even the new stuff recently installed, and I don't see how to go about doing this.
