I heard something on the news about clamping down on ticket websites but I understand the issue now.
DD was very kenn to get tickets, being released today, for a gig she wanted to go to.They went on sale whilst she was at school so asked DS to try and get them for her, with DH’s credit card.
I came back from work to find that 2 tickets had cost £270! 
I found 2 tickets for under £70 on other sites. DS was concerned about the price but they were a Birthday present and he told me he’d been lucky to get them as, ‘there was a timer and lots of people looking at them and hardly any left’. DS has AS and is very literal though many people must be duped by these tactics. 
They are non-refundable though apparently I can sell them back on their site. 
Does anyone know if they buy back at the same price? I assume the booking fee disappears and they charge the next punter the same fee?
