I renewed my Buddy Pass for $299, unlimited skiing at Breck, Keystone, and A Basin and a total of 10 days at either Vail or Beaver Creek. I think the first year they are about $20 more. They also have a pass with no Vail or Beaver Creek days for about $50 less, or you can add 10 more Vail/BC days for $200.
They were on sale in the spring, and I expect them to be on sale again in the fall. They claimed the ones in the fall would have more blackout days at V/BC.
You have to buy them in person.
Last year Vail also had a deal where you could buy 10 days for $319.
I'll go back to lurking now.
