after more testing I found things very randomly.. if I change frequent user to "no"... then it will actually show $10.10 but it still disregards the size of the products
and if I set location to that i want to send item to Melbourne 3000 it will not shows satchels price,it shows only labels price.

I then try different postcode in melbourne e.g. Glen waverley 3150.. it doesn't show both labels and satchels for fastway!!
