That will work for adjusting rates per range. I have that working.
My problem is that you have a minimum order of 12.
Formula could be: 1-99=500;100-199=400 etc.
1-199=500; This generates: (quantity * 500)
but I want to accept orders only if they are more than 12.
Now, if I cannot do that, then my only other option is . .I can accept your order of less than 12, but I'm going to charge you for 12.
Make sense ?
Is there a detail list of formula expressions ?
There is an option: 'Min. Order total Amount' on module CAT_StoreSettings. But I guess, you can use this option only, if you sell one product.
To ensure your customer orders at least 150pcs and can select each other quantitiy over 150, you must create a product bundle:
1. Create a configurable base item2. Add two slots3. Preselect the product with a quantity of 150 to the first slot4. Preselect the product for the second slot 5. Turn on the option: 'Allow order quantity selection for components of a configurable product' of the itempane module
You can find a sample scenario in chapter: Bundled Products
