[ic] limited hndling fee

[interchange-users@icdevgroup.org (Steve Streich)]

I'd like to add a handling fee for orders unders a certain dollar value,
maybe 25.00.
I am figuring maybe 7% if an order is under 25.00 and 10% if an order is
under 15.00
Anyone have any suggestions on how and what would be the best way to do
this.
I have ahandling fee added to shipping however it's a pain to have to
refund/credit the amounts when and order is above the 25.00
Thanks
Steve
