Hi,
We will be shipping in boxes of 20. Each box will be charged $10 for shipping. This means anyone ordering upto 20 items will have to pay $10 for shipping. From 21-40 will have to pay $20 etc.
I can do this in a crude way in a table by going up to, say, 500 items but I am sure there is a shorter, and less error prone way to say that each 20 items will be charged $10.
Can someone let me know how this can be done, assuming it can be?
thanks in advance!
