AbleCommerce Shopping Cart Software

Hello, we are shipping oversized items from a warehouse where shipping for EACH item is $300.

Is there a simple way to set up a shipping method for this?

Currently we're using "Vary by Quantity" and listing the multiples: As you can see, this is not very extensible. If someone wants to order 20 of the items we would have to make sure we have a min/max of 20 and a rate of $6000.

Is there an easier way to handle this situation: "Each item from warehouse x has a shipping charge of $300 applied to it."

Thanks in advance.

In our current implementations you have do it as you already mentioned above. You will need to create min/max levels. Perhaps you can try to put some code to automate this process of level creation to create suitable number of levels automatically instead of creating them manually.
