The one that I follow is always checking resale tickets first for events on Ticketmaster, especially rock concerts. The reason is that the mass majority of the time you can pick absolute bargains vs full price tickets as people just want some of their money back.
I recently went to see My Chemical Romance at the biggest stadium in the UK. It cost me just £42. When I had previously looked into going tickets were upwards of £100. You can read that review here. I’ve done it previously with football tickets too when visiting Milan and Dortmund.
What’s a life hack that you use?
