I'm using WP-E commerce plugin for an online food order shop and they delivers food in many ways. There is a requirement that if a customer order some foods which costs less than a certain amount then automatically add a delivery charge, for example if the total price is less than 10 GBP then add 2 GBP delivery charge (total=12), otherwise no charges. This is not like shipping. So, is this possible and if so then how can I add this ? Any kind of help is highly appreciated.
