Once again, Lollapalooza will release a few discounted "souvenir" tickets the week before early bird admission passes go on sale. Three-day passes will be $75, much lower than the early bird rate of $200 and the regular admission rate of $235.

Lolla fans got the email yesterday that the super secret souvenir sale is happening “sometime this week.” With no idea or warning as to when, some fans have been faithfully refreshing the Lollapalooza ticket page since yesterday morning.

Once the sale goes live, the tickets are expected to sell out within minutes. So good luck to everyone going crazy on Twitter right now. Update 3/21 at 5:01 p.m.: It's over. Looks like it hit about twenty minutes ago and was sold out almost instantly.
