Interesting… I bought beans for $15 from Bar Nine just a few weeks ago. Also, the prices on their website are all $15 or less. That said…
Now that you mention it, I do have a vague recollection of paying ~$19-$20 for a bag the first time I went. I also recall the bags looking different back then. Examining the website closely, moreover, it looks like they’re selling 250g bags, which would be ~8 oz. At that price-to-weight ratio, one would expect a 12 oz bag to be $22.50.
I’ll have to double check next time I’m there. Maybe Bar Nine beans aren’t the deal I thought they were.
