In the final step of the purchasing process, you are required to fill in your card details and complete your purchase.
Once the purchase is successfully completed, a message "Your order is valid" appears, along with the "Order Number."
Additionally, if you hover the cursor over your username, the option "Actions" will appear, which will present you with the history of your actions (valid or invalid actions).
Finally, in your email inbox, you will receive a purchase confirmation email that will mention the order number and details of the purchase.
