Safeway has Goose Island Matilda on sale for $6.99 for what appears to be 750ml. When I was in Chicago a few months ago, these were going for $9 at Binny's. I bought one a couple weeks ago and it rang up as $9.49, and I had to go back to customer service and get my money back. If you buy six, they are $6.30.
My friend who is a wine/spirits rep in Chicago says people there consider it to be sort of run of the mill, and didn't have favorable things to say about Goose Island as a company but that sort of inside baseball stuff I don't care about. I think it brings a nice amount of welcome funk, in that it smells vaguely like an old gym sock.
Also, San Diego's Ballast Point's excellent Sculpin IPA has been sale for $6.99 a bomber (22 oz) at the Wilsonville Costco now for nearly 2 months. I saw this for $12.49 a bottle at Otto's last month when I stopped by for a curbside hot dog and some sausages from their butcher.
