Can I apply a minimum order value?

It is possible to set up minimum purchase rules within WooCommerce. There are many criteria for setting rules in your online shop. Example criteria include a total number of items, items of a certain type, or an amount. When a customer takes a basket through to the checkout the contents of the basket are checked against the rules and if the rules are not met a message is returned. The customer must amend the basket so that it complies with the rules before they are able to complete the checkout process.
