inconsistent behaviour with new multi-location shipping rules and CarrierServiceAPI

Hi,

 

There seems to be some inconsistencies with the way Shopify treats manually created rates and CCS rates when the store has multi-origin shipping activated.

 

Say i had

product A - list price $8 - only available at location A

product B - list price $8 - only available at location B

 

and setup a single delivery profile which contains all products and all locations, in this profile i setup 3 rates

1. standard shipping, for orders $0-$10 - $10

2. free shipping, for orders > $10 - $0

3. App implemented using carrier service API

 

If i place 1x product A and 1x product B in the cart, Shopify will send two requests to the App, one for each product as they are in different locations. However, the two rates setup in Shopify will be calculated off the entire cart total and show free shipping.

 

Few issues here:

1. any apps using CCS won't ever see the entire cart contents now in this situation and unable to apply a generic rule such as free shipping > $10 (for the entire cart), and any merchants who have been using an app to achieve customised rules (for example free shipping > $10 but for a given postcode range only) can no longer achieve this. Furthermore as some merchants have unwittingly upgraded their stores to use this, they cannot go back and hence they lose the ability to control their rates.

2. the behaviour is inconsistent and causes confusion.

 

Anyone have any suggestions as to how we can get the original functionality back?
