You could in theory grab tix to the single non-cycle performances of Siegfried and Gotterdammerung (still available through the SF Opera website, or by calling the box office), and have yourself a "discount cycle". You'd end up seeing them out of order (since the singles of Siegfriend and Gotterdammerung are showing before the cycles start), but you'd save almost a thousand dollars relative to what you would've paid for a cycle -- there was a "mandatory donation" that was required in order to buy cycle tickets.
I am selling these two tickets at face value, $135, the same as the price to purchase similar tickets for the single shows. I'll consider a slightly discounted price, if that's the only offer I get, and the offer is payable promptly in cash.
Feel free to pass on this info to anywhere you think somebody might be interested.
