I'm sure many of you know this, but I didn't see it posted and I just discovered this, so I figured it might be useful for someone else out there.
Evidently, Costco Business Centers have their own coupon book, not unlike the regular monthly coupon book for standard warehouses.
Any Costco member can shop at a Costco Business Center. However, being geared towards businesses, much of the inventory may not be suitable for most individuals. For example, they have a sale on a 6 lbs. tub of Nutella.
However, they still have stuff regular households may benefit from. I'm going to go get a Lifetime 6 ft foldable table that's on sale. So I'd encourage people to check it out.
Important: Some products may be available at both Business Centers and standard warehouses, but per the info I got at my local store, if it's on sale at the Business Center and not the standard store, they will NOT price match. FYI.
