I would think certainly. It would probably get you a few more bottles than just a sixer. Throw up an ISO asking for a $4$ trade.
I think this is a perfect trade. You are over on $4$, but it is going to cost them more to ship bringing it back to reality. My most common trade is FW "boxed" beer for a 4 pack/6 pack of midwest beer. Only issue would be the availability of Merkin in the Chicagoland market. I know it was distributed there, but not sure how tough it was to get.
