A shipping module which calculates shipping depending on what range the subtotal falls into. Permits up to 8 ranges of subtotals to be set (eg. 0 to $20, $20 to $30, etc) and a different shipping charge can be set for each range to be established. Different ranges and shipping charges can be set up for as many different shipping methods (eg. UPS, Airmail, etc.) as you want. Individual products and categories can be configured to have free shipping and/or have additional handling charges added.
