I need a customized shipping module for my WP website. Currently I use wp-ecommerce plugin but it does not work for my requirements. I have 2 categories of product: Ionizers and needles. Domestic shipping is free International shipping is $[url removed, login to view] for purchases of needles only, $60 for purchases below $2000 and $120 for purchases above $2000. Would need a customized solution.
