For most products, this process is instantaneous. When an order is finished and the payment is complete, the key will be sent to your Kracer account inventory under the license keys menu. Though for community sales (they are not located in the main marketplace) can take a bit more time (mainly about 8 – 48 hours). The delivery time is listed in the quick description (above the “Add to cart” button).
