I'll be in Oahu next week, and plan to stop by a warehouse club to pick up a few goods for while in Hawaii, stock up on mac nuts to take back to the mainland, etc. Notice that there are several Costco's and a Sams (have a membership at both, for now). Any advice as to whether any particular store (of the Costco's or Costco vs Sams) is preferable (better selection, less crowded, etc.), or days/times when I should avoid them (e.g. Saturdays). Thanks in advance for your expertise.
