Costco is one of the most beloved retailers in the country, blowing away its members with its great value on bulk items.

Customers swear by the olive oil, rotisserie chickens, and even the golf balls made by Costco's house brand, Kirkland.

But not everything at the retail giant is a good deal. To some reviewers, for example, Kirkland's light beer tastes as cheap as it costs, while perishable foods like milk or fresh produce might spoil before you have a chance to use all of it.

We consulted personal-finance experts and accounts from Costco shoppers to compile 33 items that are definitely worth it at Costco and 14 others that you should find at another store.

Here are the Costco products that are worth your money and the ones you should avoid at all costs.

Buy: Rotisserie chicken

Ivo Parashkevov, a creator of Charlie, a personal-finance artificial-intelligence bot, said that at $4.99, Costco's cooked rotisserie chicken is a loss leader, as well as a bargain he doesn't want to pass up whenever he goes to the store. Add a premade salad, he said, and "that's a dinner for a family of four right there" for under $10.

Buy: Kirkland bacon

Costco's Kirkland sliced bacon has a rating of 3.3 out of 5 from reviews on Consumer Reports, with negatives that have more to do with the amount you need to buy at once (the bacon packs come in bundles of four) than the flavor.

Skip: Fresh fruit and vegetables

For many shoppers, when you buy fresh fruits and veggies in Costco quantities, you might as well be shopping for the compost bin.

Costco has an abundant produce section, with lots of fresh and healthy choices. But the quantities of perishables are too much for most households. You're probably better off buying fresh fruits and vegetables in smaller quantities at the supermarket.
