Shopping carts - how do I get several?

[pbuild]

Hi!

 

I'm trying to deploy Prestashop 1.5 for a marketplace-like solution. So I have multistores set up. Stores have common products, but each store sets its own prices, each has its own cart, and each will check-out separately. (When I tried with common cart, the same product from different stores produced one line in the cart, and messed up the prices.)

 

My problem is that I need a page where the user can see /all/ his/her carts, not just the one for the current context, whether the user is logged in or not. I've looked at the code a bit, and looked at the cookies being set, and I'm stumped. (Probably because I'm still a newbie.)

 

If I add items to the cart in two of the shops, I get two carts (sensibly enough), two cookies, and two entries in ps_cart with different id_guests.

 

Can someone point me towards how I can get all carts? I don't see where having multiple cookies is handled... (*confused*)

 

Thanks!
