The items will be emailed to you. The seller sends the items to you and you receive them.
1. Immediately after the purchase process is complete
If the seller offers immediate delivery, do not close your browser (or tab) and wait for the order to be confirmed and completed. Next, just click on the "Get Key" button - you can collect your item.
2. Delivered to your email address via shipping email
If you don't receive your item in your browser right away (the seller doesn't offer instant delivery, there are some delays, etc.), you can always check for the item in your mailbox using the email you provided at checkout.
