Thanks. We only ship to Oceania which is New Zealand, Australia and the Pacific Islands. What we have is options which are different sized courier bags and then courier stickers for different weights and zones.
Then the products have been assigned a weight and we use a rule of thumb where some items we may make a $ and others lose a $. It all works out ok in the end.
I think the system doesn't allow for this and maybe there is another module to be purchased.
