I had placed a 'Sale Order', selling one ticket and the only date option for delivery was showing as 7th January.
I saw the note that it can be changed later so I proceeded.
The issue is the tickets that I had purchased would be delivered to me on 8th January and only on 8th I can share it on StubHub for the sale order.
But, not sure why, I'm unable to select 8th January as the delivery date.
