I have been struggling hard from a few days to find out a way for multi shipping of products depending on product type (type is not magento's type where as it is custom attribute i.e type can be grocery, non-grocery)
so, let me explain my problem:
I have two types of items in my store, one are grocery and other are non-grocery. When a user add these items to cart, I need to show him two groups of products(grocery, non-grocery). The grocery items can be shipped in one hour while others cannot be. So I need to show user separate shipping methods available for both the groups i.e user can have options as MethodA, MethodB, MethodC for grocery-group and MethodB, MethodC, MethodD for non-grocery-group.
Note: The products as grocery, non-grocery are separated on the basis of some flag in product attributes, moreover the address will be the same for each group.
I didn't find any extension which can do so, from where should I start? should I override the functionality of Multi-shipping? Please suggest me the ways to get it done!
