An instance variable @x survives only for one HTTP request. When you move from the store controller to some other controller, most likely, you're sending another HTTP request (as opposed to an AJAX request, typically) which clears out all instance variables. This clears out @cart and you dont see your data.
For each request that you want your @cart to survive in, you need to populate it with values in the controller. How can you do this? use before_filters maybe. depends on your setup really.
