Atom Cash basically functions like a store credit. If you cancel an order, you’ll have the option to choose between an exchange for Atom Cash or a refund back to your original form of payment. If you choose Atom Cash, the full dollar amount of the order will be deposited and stored in your Atom account (including order fees). If you choose a refund, order fees will not be included in the refund amount.
Atom Cash never expires and can be applied towards any future order.
