Is it possible to have courier charges that increase with order size (amount)? Please let me know - as I really need this function.
You write in the About_bandedCouriers: "Banded Couriers is based on the principle of diminishing costs, ie. the larger the order the lower the courier charges. If you have courier charges that increase with order size this plugin WILL NOT WORK for you!"

Hello all!
I know this problem can be solved easily by someone in this forum. Please let me know which line to edit, and what to edit. I just need a little help by one of you, guys! Here is the code:

It is hard to say, what should be changed, as we aren't author of this plugin, so we don't modify it. We have our plugin doing something similar, but it is payed (http://opensolution.org/os/templates/en_plugins.html#DK). Maybe first try to ask author of this free plugin to make this modyfication.
