When creating your post, be sure to select the Ticket Type as Barcode Image/PDF. On the second page right after you select the quantity of tickets, you are instructed to upload the image of the ticket. When a request is accepted, the image will be sent to the buyer and the tickets will be considered delivered. The seller does not need to mark the tickets as 'Delivered', the buyer will mark as 'Received' once they download the tickets.
Please keep in mind that after a Barcode Image or PDF ticket is shared, the sale cannot be cancelled since the buyer is in possession of the ticket and would need to be re-sold by the buyer if it is no longer needed.
NOTE: If the ticket was delivered to the original purchaser (seller) via email, it is always recommended to also forward that email directly to the buyer to act as a back up way to access the ticket upon arrival. Please use the "Message User" option on your sale to ask your buyer for their preferred email so you can forward the email to them.
