I agree the movement is likely nearing saturation on total number of microbreweries. However, $10 +/- a few dollars, for a six pack, is not a problem. The mediocre old domestics cost $7 to $10 around most of the US. Paying more is perfectly fine for a superior tasting product. Product price scaling works that way in most consumer goods, it makes sense.

No they don't, not even close. The beers you're referring to cost that for a _12_ pack. 6 packs are ~$5.50, and you can walk into a bar and get a draft old domestic for around $2.00. Wherever you're buying your e.g. Bud Light, it doesn't represent "most places".
