I’m having problems setting up my manual shipping rates. We have a courier contract and the rates look something like the following:
for consignments of 0 to 10 KGS there is a consignment charge of Â£8.20
for consignments of 10 to 20 KGS there is a consignment charge of Â£9.40
For these there is no per KG charge. So consignments of 4KGS and 9KGS would be Â£8.20 and 14KGS and 19KGS would be Â£9.40.
Above 20KGS there is a per kilo charge of Â£0.28 per kilo for each kilo above the 20KGS.
So for example a consigment of 29.7KGS should be = 9.4+(9.70.28)=Â£12.16
for some reason the cart is calculating it as Â£8.32
Using another, simpler, shipping method where we get a consignment charge of Â£9.1 for 0 to 10 KGS and then 0.72 per kilo above 10 kilos, should give for the 29.7KGS:
9.1 + (19.70.72) = Â£23.284
but cs cart is showing Â£21.38 which also makes no sense. I have no product-related charges and all the above are done just using the weight dependencies.
Many thanks for any guidance on this. I have a feeling I am missing something.
