Sometimes, the calculated delivery rules lead to displaying a non-"merchant" delivery amount on your checkout page.
For example, if the calculated delivery is 5.83 EUR and the cart contains 30 EUR of products, the total amount will be 35.83 EUR.
Psychologically, it will be more pleasant for your buyer to see an amount of 36 EUR.
To activate this automatic rounding calculation, simply go to "Settings" then "Delivery" then check the dedicated box (don't forget to save).
