I have given small product free on purchase of big product.
Items get added in cart but while proceeding to checkout free item sometimes displays and sometimes it disappears.
Can anyone explain its shopping cart's functionality. How it get functioned.
Below is the page where item get disappears.
Can anyone explain
$_item = $this->getItem()?
When I refresh the page that time free product is getting deleted from sales_flat_quote_item table.
Is there any code if product price is zero then it will get deleted from sales_flat_quote_item table?
