Tomorrow there's a pre-sale to concert I want to buy tickets to - a concert that will definitely sell out. There's a "Cash App" and "Chase Cardholder Preferred" pre-sales, both at the same time. The former is if you have a Cash App card (which I have). I'm assuming the latter is just the first couple of digits to my CSR card.

I'm so unbelievably sick of getting screwed over by concert pre-sales. I have both an Amex Platinum and CSR cards. Any suggestions of which concierge would be better trying to get me tickets? Should I put both up to the task? Should I also be trying to get tickets as they are getting tickets? Not sure what success rate is with using the concierges for this type of thing. Thanks!
