In many ways, joining Costco (Nasdaq: COST) is like buying a gym membership. For some people, just joining is enough. They rarely (or never) take advantage of what they paid for because just joining felt like a step in the right direction.
That, of course, is silly. If you don't go the gym you won't get in shape. The same is true of Costco. If you don't use the warehouse club you won't actually save money.
