they were pretty widely available though there is not all that much around anymore. 10 dollars each, should not be hard to pull with anything that isn't super widely available. plenty of CCB stuff should get it done. 2 is the best by far in my opinion so definitely go for that one. don't forget about barrel noir which is also great.
I had no problem getting someone to set me the whole set (to date) for BCBS, $4$, within the last three weeks.
They should go $4$ with other interesting shelf beers. Around $10 to $11 per bottle. No. 3 is the best of the series in my opinion.
