She sold more tickets for her Wembley shows than Beyoncé who had super packed stadium. It all depends how many sectors with obstructed view you have open, and if I recall correctly Taylor had quite of them? It’ll sell out in hours if not minutes lol. Last time she had sold 210k tickets in the UK, 120k in Ireland. Her shows in Berlin and France sold out instantly so you’ll also have people from there trying to snatch tickets.
