Rethinking Your Costco Grocery List: What Not to Buy for Better Savings

Costco, known for its bulk items and unbeatable prices on certain products, has become a staple shopping destination for many. From the unbeatable $5 rotisserie chicken to the vast selection of electronics and clothing, the allure of Costco deals is hard to resist. However, not every item on the vast aisles of this wholesale giant is a wallet-friendly option, especially when it comes to grocery shopping.

While the bulk-buy philosophy is perfect for non-perishables and households with high consumption rates, certain items on your grocery list might not be the bargains they appear to be. Here’s a deeper dive into eight grocery items you might want to reconsider purchasing at Costco if you’re looking to save more on your grocery bills.

1. Milk

A staple in most households, milk is often grabbed during routine Costco runs. However, depending on your location, you might be paying up to double what local supermarkets charge. For example, while Costco might price a gallon just under $4, supermarkets like Kroger frequently have half-gallon jugs on sale for only $1.29.

2. Cooking Oil

Costco offers large quantities of cooking oil, such as their Kirkland Signature two-pack totaling six liters. However, oils such as olive and canola have a limited shelf life and can go rancid within a few months. Unless you’re running a restaurant or cooking for a large family daily, you might not use it all before it spoils.

3. Fresh Produce

Buying fresh produce in bulk might seem like a good idea for a big family, but the reality of perishables is that they need to be consumed quickly. Costco’s large packs of fruits and vegetables often lead to waste if not used promptly. Consider buying smaller quantities of fresh produce or opting for frozen alternatives which can be stored longer.

4. Herbs and Spices

Spices lose their potency and flavor over time. The EatingWell Test Kitchen recommends using ground herbs and spices within a year for optimum flavor. Purchasing these in bulk from Costco might lead you to have more than you can use before they degrade. Smaller, more frequent purchases from local stores ensure fresher flavor and less waste.

5. Raw Chicken

While Costco offers great deals on certain meats, raw chicken might not be the best buy. You can often find chicken breasts or thighs cheaper per pound at local supermarkets, especially when they go on sale. Buying in bulk and repackaging at home can be more economical and tailor-fitted to your consumption needs.

6. Sandwich Bread

The bakery section at Costco is tempting with its array of fresh bread. However, the quantity required to obtain the lower per-unit cost might not suit smaller households. Additionally, grocery stores frequently run promotions such as “buy one, get one free” on bread, offering a better deal without the commitment to volume.

7. Bagged Salad Kits

While the convenience of Costco’s large bagged salad kits is undeniable, the price per serving can be similar to what you’d pay at a standard grocery store, with less variety and a higher chance of waste due to the large portion sizes. Smaller packs or buying individual salad components might provide better value and reduce unused leftovers.

8. Soda

Buying soda in bulk at Costco might seem like a sensible choice, but grocery stores frequently offer deeper discounts, particularly during holiday sales. Keeping an eye on local store promotions can often net you better savings on these beverages.

Smart Shopping Strategy

Being a savvy shopper means knowing when and where to buy. Costco’s bulk deals can be unbeatable for many items, but for others, local supermarkets might offer better savings—especially when you consider the shelf life, consumption rate, and storage capacity of your household.

In summary, while Costco provides excellent savings on numerous fronts, a careful assessment of prices, consumption habits, and product perishability will ensure that your trips to this wholesale giant are as cost-effective as possible. Shopping smartly means not only looking at the price tag but also understanding your household’s needs and how quickly you can use what you buy.
