<prompt> Human: As title. Buying in bulk is almost always cheaper but Costco bulk doesnt necessarily mean its cheaper with everything else being so competitive, especially on dry goods that I can order online. Theres also the bulk fresh goods items. Its all fine and good that I can buy a whole tray of lettuce heads for cheap but they will expire long before I can use all of them, which makes it less efficient from a cost perspective since you dont get the full value of what you pay for  <response>: Theres quite a few items I routinely buy that are cheaper at Costco than most everywhere else, and there are quite a few items I routinely buy where CostcosKirklands items are as good of quality or better than most everywhere else. I also have an executive membership and at the end of the year Costco pays me to be a member. Cant beat that with a stick.
