Ha yeah! Wonder if the ticket office has a formula of when to set sales levels based on current sales? As in if they've got 5,000 left with a month to go do they bump it down a level?

Boxing Day tickets now on sale to anyone with a purchase history
Good luck actually getting into the stadium with one of those tickets.
A lot of resellers like that advertise tickets before they actually have them and are trying to source them whilst advertising them.
Are you friends with anyone that is a season ticket holder? If so they can buy season ticket guest tickets for this and save you the Bronze membership fee.
