I am using WooCommerce and would like to add certain fees to the customer's final total depending on their subtotal.
For example, if their subtotal is:
Less than $8.99 | $7.99 fee
$9-$24.99 | x% fee
$25-$49.99 | y% fee
$50-$99.99 | z% fee
I have found documentation from the developer that adds a pre-determined % surcharge correctly, but I would like to have more precise structure. You can see it here: http://docs.woothemes.com/document/add-a-surcharge-to-cart-and-checkout-uses-fees-api/
Can anyone help me out?
