It looks to me like a third party just scraped a lot of the content from northernbrewer.com. Some are more obvious than others. The prices are too good to be true as well. I was about to buy a bunch of stuff ‘on sale’, but it’s just too sketchy, I think.
It would be nice if it were legit, though. Those are some good prices.
Scam. If you do order something to test it out, set up a virtual credit card and trash it afterwards.
