Order products from different suppliers

[bluestyle]

Hey Guys, I want to use Prestashop for my online shop but the problem is that I will have products from different suppliers.

 

Question> How can I identify the different shipping costs of different suppliers?

 

so like the following: 2 products in 1 shopping cart:

 

• product1 - carrier1 - delivery costs $2,95
• product2 - carrier2 - delivery costs $6,95
   
• total shipping costs $9.90

 

but if the customer has 2 products in his cart that are delivered by the same carrier it only has to charge a 'single' shipping price

like the following:

 

• product1 - carrier1 - delivery costs $2,95
• product2 - carrier1 - delivery costs $2,95
   
• total shipping costs $2,95

 

Is there any module to solve this problem?  HELPPPPP!!!! Thanks
