Costco man storeOne employee said they tended to skip the gallon-sized mayonnaise jars.

  • Business Insider reached out to Costco employees to find out what items they would never buy at the store.
  • Most workers cited the chain's bulk sizes as the reason they'd skip over certain products - especially perishables.


Costco products are known primarily for their bulk sizes.

The retail chain is also famous for selling just about everything, from giant teddy bears to enough pizza slices to qualify as the 14th largest pizza chain in the US. There are always a few surprises thrown in with the staples, too.

But Costco employees themselves know firsthand which deals are worth it - and which are best to skip.

That's why Business Insider spoke with 27 Costco employees to learn what products they never buy at the store. Eight of those employees - who hailed from California, Kentucky, Nebraska, Washington, Minnesota, Ohio, and Florida - didn't have a response for us. They all said that they buy everything at the chain.

"I can honestly say I can't think of anything I wouldn't buy," a worker from Ohio told Business Insider. "Some items are out of my price range. But, if I had disposable income, I would buy everything from Costco."

Here's a look at which products other employees tend to skip:
