i'm trying to make the carrier price dependent of the product quantity. i have to calculate for each product a carrier price of 2.20EUR. i only got one carrier/payment method. and if the amount of all products is '3' or bigger it'll cost 5,90, if its bigger than '10' it'll cost.. .and so on. the first problem is more important than the second.
for example
1st Product 39EUR (2x) 2nd Product 20EUR (1x)
Sum 98EUR Carrier 3x2.20EUR = 6.60EUR but quantity = 3, so Carrier = 5,90EUR Total 103,90EUR
i tried to modify the throwPaymentCarriersPrice-function, maybe i missed something but it didn't work at all.
