Getting accurate shipping costs with multiple products from multiple sellers

[ghl.karan]

I am using Prestashop for my online marketplace where multiple sellers can list and sell their products, each with their own set of shipping carriers offered.

 

E.g. seller 1 may charge £10 for next day delivery and £5 for economy 3-5 day delivery. Seller 2 may not even offer next day delivery, but may offer economy delivery for £3.

 

So, if a customer decides to purchase products from both these sellers on the marketplace and goes to checkout, only seller 1s offered carriers show up.

 

How can I get the cart to show carrier options separately for each product?

 

Thanks very much for your help
