I am building a Carrier module in Prestashop 1.6.x and at the moment I am having a problem with the abstract method getOrderShippingCost().
It is called 6 times and I cannot find out why.
I need a way of tracking why is it called that many times.
Any help is appreciated!
I got it why it is called multiple times.
The method is called as many times as many carriers you've got registered in the shop.
