funny you should ask, i just picked up a bottle of Raspberry Sour for $15.99 here in DC. i'll probably try it this weekend. only one bottle left, i was tempted to grab both but couldn't justify it for the price. BA reviews are very positive but people are stopping short of calling it amazing. t'was good enough to get me to try it. sounds like folks out west are paying $10, lots of comments along the lines of "hands-down best value in sours today."
also picked up a 4-pack of Kirsche Gose and a single of Weyeerbacher's Tarte Nouveau. an all-sour beer run!
also, i've got 4 of my own sours coming online... i really shouldn't be buying commercial sours, but you just can't have enough pucker-beer on hand now can you?
