Corporations don't like it when you share the stuff you paid for guys. First Netflix cracked down on password sharing, now Costco is doing something similar when it comes to its memberships.

This stricter enforcement of rules from Costco doesn't impact just Michigan shoppers, but it could affect how you use your membership in the Mitten nonetheless.

Effectively, Costco wants members to be the ones paying the bill in the checkout lane, not your cousin Ed who borrowed your membership card.

Costco is aiming to enforce pre-existing rules surrounding its membership more closely to preserve the integrity of the membership experience.

It's similar to Netflix users who may only watch one show on a friend's account who uses the service all the time and doesn't mind sharing.

But much like the decision to use self-checkout kiosks to save on paying cashiers, Costco is watching those profit margins on memberships. The circumstances of how paying customers come to use the products don't matter as much as the bottom line.
