Today is not Red Hill, its Wires, and its also the option to buy tickets and add a subscription.
So today you can go on without a code, check for seats and if you like them, buy them along with buying a $50 subscription. This is what folks should have done (Mikal, ouizy for example) rather than buy the membership ahead of time and get the code. If you weren't in yesterday's presale, you could look for tickets today and not have to buy a membership subscription unless you liked the tickets offered and took them.
So today the entire buying public can look for tickets, and trust me brokers have snapped up good ones and bout the added membership. $50 on top for 4 GAs is nothing to them.
Also keep in mind that its a presale and not every ticket in the building is made available. Many don't get released till next Tuesday.
