Membership at costcos?

Do you have to pay for a membership to shop at costcos like you do at sams club?

Yes you do, but I don't think there's one close to Owosso.  There is one in Lansing.

Thanks,  theres also one in GR on 28th st right next to 96.  I pass it  every week on my way to see my mom in Fremont.   I was just wondering if it was any better price wise than sams

Yep and its $50.  I think you can go to the desk and ask for a one day pass and they will let you in.  Best of luck,
