Hello all,

when I used a rule coupon greater than the product price, the difference is also used to reduced the shipping fee.

Example :
- product price is 25€
- rule coupon is 30€
- shipping fee is 8€

> At the final, customer will pay : 25-30+8 = 3€
> Instead of 25-30=0€ then +8 = 8€

Perhaps I missed a checkbox somewhere in the configuration ???
If it is like that by default, can someone tell me which php file(s) I have to modify in Isotope repository ?

Configuration :
- Contao 2.11.5
- Isotope 1.3.5 rev.8 (with wfIsotopeStockManagement)

Thanks in advance.

Regards,
