Hi,
I would like to add a fee at checkout that is calculated based on the Quantity in the cart. It should show on on it's own line.
The fee would be $25 * Total QTY of all products Added to the Cart.
What would be the best way to accomplish this?
Example:
QTY | Product | Total
-----------------------
1 | Product A | $125
2 | Product B | $250
Service Fee: $75.00
Total: $450
