From where to link the shop?

Now just want to get to the point of adding products to the cart because the client wants to sell and bill for other routes.
The problem is I do not know if it is saved in the database products are in the shopping cart of a buyer.
You may be saved in a particular table or there is no way to stay registered products in the shopping cart?

I've consulted by ticket but can take up to 24 hours and is a very urgent issue

Hi,

I am not sure, but I think there are two way this can be done:
1) Customer has to create an account and then products will be save to this account.
2) Cookies!. But I am not sure about this.
Maybe you can test with an account? To see what happens?
