Using coupons at Costco?

HI Everyone :)

I was wondering if you can use manufacturers coupons on items at Costco? also wondering if you can use coupons on a product there that already has a manufacturers rebate on it? Has anyone tried this before?
Thanks!

Costco does not take any coupons other than their own. This was actually just posted not that long ago.

yup...scbpooh is correct. I tried it once....and never again..lol

I tried once too, they don't take them except their own coupons.

lol i tried once too =/

Thanks good to know :).....I've only beeen an SC member for a month ...sorry I missed the previous post...I tried searching before I posted this and nothing came up except costco coupons. :(

Costco, by definition, is not a retailer - They are wholesaler. The coupons are only applicable to retailers.
