Purchase Flows​

When browsing our catalog, users have two options to purchase content:

Add to Cart​

The "Add to Cart" option allows users to add items to their shopping cart while continuing to browse the store. This is ideal for users who want to purchase multiple items in a single transaction.

Buy Now​

The "Buy Now" option adds the selected item to the cart and immediately redirects users to the checkout page to complete their purchase. This streamlined approach is perfect for users who want to quickly purchase a single item.

Both options provide flexibility to accommodate different shopping preferences and scenarios.
