I have been trying to acquire some spotted cow as a gift for my father who is a Wisconsin native and isn't able to travel much anymore. I'd be happy to pay anyone who would be willing to send some to me. If there was a request for any beer from Iowa desired, I'd also be happy to reciprocate!
Definitely stick with trading as the only option. Exchanging money for beer is forbidden on this site and you could be banned.
Are you in Iowa? Not that you're in Eastern Iowa and as close as me for example but if you are able, all you have to do is barely get across the border and gas stations/grocery stores will carry this and you could get it done yourself.
