12 Unexpected Costco Products Superfans Say They Would Never Buy Again

While Costco offers many products and deals fans love, not everything at the famous bulk retailer is a hit.

Costco superfans will tell you that the store's rotisserie chicken is a safe bet or that a lot of the snacks are worth it. 

But some Costco items can be a miss. Here are a few that some superfans will tell you it may be better to avoid buying to unlock the true value of your membership.

Costco replaced its berry smoothie at food courts nationwide with a mango smoothie. However, many customers urged others to avoid wasting money and skip it altogether, so much so that Costco discontinued the drink.

Some described it as tasting like spoiled baby food, and even kids rejected the less-than-tasty treat from the food court.

So, lesson learned: Stick with the traditional hot-dog-and-drink deal at the Costco food court.

Keeping your dishes sparkling clean may not be the easiest thing to do if you buy the Kirkland Signature Dishwasher Pacs.

Some superfans have complained that the dishwasher pods don't get their dishes as clean as the name brands Costco carries, making this a product you can skip.

Produce can be hit-or-miss at Costco, depending on what you're looking for or how much you plan to use.

You may want to avoid Costco's produce section if you live alone or won't finish it quickly, because it could spoil before you get through a bulk amount of bananas or pears.

You may like picking up new books from Costco's book table, but books are one item where you may not save much by buying them at the warehouse retailer.

Though the retailer announced last year that it would stop selling books, they return for a limited time during the holidays.

Before you pick up a new book at Costco, compare the price with online retailers such as Amazon or Target. You might find you can get a better deal online than at Costco.

Like other grocery stores, Costco has its store-brand version of milk that you can buy.

But you might be surprised that Kirkland Signature milk is more expensive than other retailers nearby. Compare the costs at Costco with those of stores like Walmart or Target to see if you can get a better deal.

You may think toilet paper is toilet paper, but some superfans think you should ditch the Kirkland Signature stuff for other alternatives.

Toilet paper may be one of those items at Costco where it's better to spend a little more and get the name brand that will hold up better than the less popular store brand.

You might think buying soda in bulk at Costco will save you money, but keep an eye on the per-unit cost.

Costco's prices may seem expensive because you're buying in bulk, but breaking down the price into a per-cost number can make comparing costs with other stores easier.

For example, a 24-pack of Coca-Cola at Walmart costs $1.16 per can, while a 35-pack of Coke at Costco costs 59 cents.

Like produce, Costco's bread can go bad quickly, so you'll want to make sure you use it all soon before it gets stale or moldy.

One of the issues with Costco's bread options is that you may have to pick two loaves and not one, so consider grabbing one loaf at the local grocery store instead.

Medications can have an expiration date just like food, so consider that when buying a bulk-size version of medication at Costco.

You may also want to do some comparison shopping when it comes to certain drugs, as you may be able to find the same amount for a cheaper price at another retailer.

Don't assume you'll automatically save money on essentials just because you're buying them from Costco.

Kirkland Signature has its own line of protein bars in different flavors, such as chocolate chip cookie dough, chocolate peanut butter, or brownie.

However, some superfans complained that the bars are hard compared to chewier name-brand versions or that the texture may differ from box to box.

A highlight for some shoppers is the chicken bakes at the food court, including chicken, cheese, bacon, and other ingredients stuffed in a pastry shell and toasted up at Costco.

On the other hand, the box of Kirkland Signature Chicken Bakes you can buy in the frozen foods section may not be up to the same food-court standards.

Instead, grab a fresh one on your way out the door and leave the frozen ones in the Costco freezer.

Another potential perishable is Costco's muffins from its bakery selection.

The muffins can be delicious and come in a variety of flavors. But superfans complain that if you don't eat your dozen muffins quickly, they'll go bad, and you'll have to toss them.

One of the great things about shopping at Costco is the store's generous return policy. If you don't like it, simply return it, and you'll get a refund.

And though Costco is a great place to save money on groceries, you may want to make a list before you go in to stick to your budget. 

Remember to try Costco's store label, Kirkland Signature, which can also help you keep some extra cash in your pocket.
