In the general settings we find the option to decide what the currency of our shop will be (for example EUR is Euro, USD is U.S. dollar).
We can also configure the number of hours for the cart and payment to expire:
Cart expiration is the number of hours after which the cart expires and is deleted. Hour counting begins after the customer's last interaction with the cart.
Payment expiration corresponds to how many hours a user has available to pay, after having been given the instructions to proceed.
