Minimum or maximum amount for shipping method
Allow a minimum or maximum order amount for shipping methods. Example, orders over a specified dollar amount does not show 1st class mail option. Or an order under a certain dollar amount does not show UPS Next Day Air. Sometimes I do not want to ship an order by 1st class mail even if the weight is low enough, but the dollar amount is higher. Or ship a $20 order for $90 in UPS Next Day Air shipping.
