Ticketmaster facilitating scalping through the resell part of their website. The purpose of this should be for people who genuinely can't go (because life happens, and it's happened to me a couple of times that I couldn't go to something for reasons that didn't exist at time of purchasing several months in advance) to recover their costs by selling at the purchase price rather than people reselling at more than double the price within 5 minutes of the presale going live. I guess they figure it's going to happen anyway so they may aswell provide the platform so they can take a second cut of fees for the same tickets instead of Trademe getting it.
It pissed me off yesterday when I was trying to buy tickets for Celine Dion for my Mum and couldn't get anything in the presale yet minutes after it went live the resell page had tickets listed at 3 times the price. My mum has wanted to see her for 20+ years and has had a pretty tough time lately so fingers crossed I can get some.
