Most states don't allow a "club" membership in order to buy alcohol. In this case, Costco is a club.
  1. Go to Costco
    Parking is easier earlier in the day
  2. Tell the hopefully friendly person at the door you're just there to buy alcohol
  3. Find the alcohol section
  4. GO CRAY
    Kirkland brand of most liquor is fiiiine. Especially if you're mixing.
  5. Check out
    If you just have alcohol they won't make you show a membership card. Just ID.
