Free Shipping over ‘X’ but still charge “Additional Shipping Charges”

If you want to use Free Shipping over ‘X’ but still charge “Additional Shipping Charges”, you can't use nopC’s built-in Admin > Configuration > Settings > Shipping >> "Free Shipping over 'X'" because it will ignore Additional Shipping Charges set on product variants.  The built-in Free Shipping over ‘X’ is always calculated last after shipping plugins return their options.   You can make this work with Shipping Director.  First, be sure to turn off "Free Shipping over 'X' " in admin.  (And as always when using SD, be sure that SD is the only Active rate calc method.)

This is really easy to do in SD – just calculate a 0 rate when the subtotal is over X!  Then, NopC will always add the additional shipping charges.  For example, here’s free shipping ($0) if the subtotal is more than $50:

Of course, to make this complete, we'll add the second Option record to provide the rate if the cart does not meet the minimum amount.  And, to get a little fancy, we’ll use the Name Expression to show the customer “Free Shipping” if none of the items have any additional shipping charges, otherwise show “Shipping”:

The second record above is a flat $5 rate, but you can of course use any type and number of additional methods/rates instead.
