Shopping Cart

As a Shopper,
I want to put items in my shopping cart
Because I want to manage items before I check out

Acceptance Criteria

Scenario: User adds item to cart

Given I’m a logged-in User
When I go to the Item page
And I click “Add item to cart”
Then the quantity of items in my cart should go up
And my subtotal should increment
And the warehouse inventory should decrement
