Go to a few online stores and see how the interface has been designed to enable the customer to order and pay for an item. How many use the ‘add to shopping cart/trolley/basket’ followed by the ‘checkout’ metaphor? Does this make it straightforward and intuitive to make a purchase.
To analyze how online stores design their interfaces for ordering and payment, visit a few e-commerce websites and observe their processes. Here are some key points to consider:

Shopping Cart Metaphor – Most online stores use an “Add to Cart” (or “Basket” / “Trolley”) feature, allowing users to select multiple items before proceeding to payment. This mirrors the traditional shopping experience in physical stores.

Checkout Process – After adding items to the cart, users typically click a “Checkout” button, which guides them through:

Reviewing the cart
Entering shipping details
Selecting a payment method
Confirming the order
Ease of Use – This approach is widely adopted because it is intuitive and familiar. Users can modify their cart before finalizing the purchase, making it a convenient and user-friendly process.

The Correct Answer and Explanation is:

Correct Answer:

Yes, most online stores use the “add to cart/trolley/basket” followed by the “checkout” metaphor. This makes it straightforward and intuitive for customers to make a purchase.


The design of e-commerce websites plays a crucial role in the user’s purchasing experience. A consistent and familiar interface can make the difference between a completed purchase and an abandoned cart. When analyzing the structure of major online stores—such as Amazon, Walmart, Target, and ASOS—a common pattern emerges: the widespread use of the “shopping cart” metaphor followed by a clearly defined “checkout” process.

The shopping cart metaphor is inspired by the traditional retail experience, where shoppers place physical items into a cart or basket before heading to the checkout counter. Online, this metaphor translates into a button labeled “Add to Cart,” “Add to Basket,” or “Add to Trolley.” Users click this button to save items they wish to buy while continuing to browse the site. This system provides flexibility, allowing shoppers to gather multiple items before proceeding to payment.

Once the user is ready to finalize their order, they click on a clearly marked “Checkout” button. The checkout process typically follows a step-by-step format that includes:

  1. Reviewing the items in the cart.
  2. Entering shipping and billing addresses.
  3. Selecting a delivery method.
  4. Choosing a payment option.
  5. Reviewing the final summary before placing the order.

This design pattern is intuitive because it mirrors real-life shopping and minimizes cognitive load. It also allows users to edit or remove items, adjust quantities, and see the total cost (including taxes and shipping) before making a financial commitment.

The consistency of this structure across most e-commerce platforms contributes to its success. Because users encounter similar processes across different sites, they do not need to relearn how to shop every time. This increases usability, reduces user frustration, and enhances conversion rates for businesses.

In conclusion, the shopping cart and checkout metaphor is a well-established, user-friendly interface design that supports a smooth online shopping experience.
