A few pointers: generally, you will have more success trying to trade brewery-only beers for other brewery-only beers. MobCraft is known for having quality issues. Despite the fact that Cyber Monday was only avilable once, this largely negates that value. It’s just not sought. Similarly, Black Betty is still available on shelves in the Milwaukee area. Nein, though more limited, was also available for quite some time. I would recommend doing more research on a site like BeerAdvocate to ascertain ideas about trade value and example offers. Sometimes, a trade just take the right set of eyes to complete. People have been known to trade quality for quantity. But you’re better off hedging your bets if its something you really want. Good luck!
