Finding a beer… emperor Julius

Hi there! I’m on the hunt for a beer that doesn’t seem to be anywhere in the state I live. I’m trying to get it as a gift for my boyfriend (he’s talked about wanting to try it a million times, but apparently it’s only sold in Massachusetts…) Does anyone on Washington state know/or has seen Emperor Julius beer anywhere? Or does anyone have any knowledge on a way I could buy some without living in Massachusetts or going there? Any and all help would be appreciated!
