title_body: Selling/buying limited edition beers online
upvoted_answer: It is not legal to ship alcohol(beer, wine, or spirits) through the mail across state or national lines unless you have a license. This has to do with each state wanting to get it's tax revenue for the imported alcohol.
  
  That doesn't mean it's not done, it's just less likely for a site that wants to stay in business to allow transactions that would result in it.
  
  I have friends that are part of "exchange programs" that are on various forums. There is a "beertrade" sub Reddit for example.
