Shipping increments for extra item
Okay here is the situation:
Two items formats: CD and LP
CD has a flat rate of $8.99
LP has a Flat rate of $13.99
Increments For CD Only int the cart:
If a cd is in the car any other CD will have the shipping of $4.50
Increments for LP only in the cart:
If only LP is in the cart any other LP will have shipping rate of $6.99
So Far so good OK
Now if the cart has 2 LP and 2 CD (just an example):
The shipping charges should be:
$13.99 + 6.99 + 4.50 + 4.50 So what I need to achieve is the shipping rule needs to pick the higher amount and based on the format of the other items add the increments
I know sounds dumb but can any one help on that I got stuck.
The increments for the same items in the cart i got but when is mixed that's the problem.
