Although organizers haven't yet announced the lineup, trusting fans snapped up 750 low-priced passes to Lollapalooza this year in a matter of minutes during a "secret sale" Tuesday.
Tickets sold out in less than a minute after subscribers were notified that the sales were live in an e-mail blast from organizers, according to NBC Chicago.
Angry fans who missed out on the deal have since taken to Lollapalooza's social media platforms and their own user networks to express their frustration with the sale structure. Festival organizers are directing the disgruntled to their early bird ticket sales March 27, where three-day passes will be offered at a discounted price of $200.
Full-price tickets will cost $230 after the early bird batch sells out.
Fans may have been frustrated not only that they missed out on the lowest-price tickets for the summer event, but also over whose hands they ended up in: Gapers Block reports that more than 70 of the first-available passes appeared moments later on ticket broker website StubHub for at least five times the original price, with some passes priced up to $999.
