For You: The Best Costco Buys for the Money Right Now
Walmart Is Best for Everyday Essentials
If you want to save money on everyday essentials like milk, eggs, bread, and pasta, the retailer's private-label brands, like Great Value, can help you save quite a bit of money. Compared to Costco, where things are typically sold in bulk, Walmart makes more financial sense if you’re living alone and don’t want to commit to bulk quantities. Plus, Walmart has thousands of locations nationwide and convenient pickup and delivery options.
The biggest downside is that Walmart has a wide selection of specialty foods or unique products like Trader Joe's. Its per-unit prices on bulk items are also usually higher than Costco's. That said, if your main goal is to save money on everyday essentials without having to buy in bulk, Walmart is still valid.
Trader Joe’s Best for Variety Foods
Trader Joe's is known for stocking fun products and unique flavor combinations, such as its iconic cookie butter, cauliflower gnocchi and crunchy chili onion peanut. So though it isn't always the cheapest option for staples, you might find value in all the interesting Trader Joe's private-label products you can find on their shelves. And since they have all sorts of ready-to-eat foods, it’s a solid grocery store to shop at if you don't want to spend a fortune on specialty ingredients.
The downside is that Trader Joe's has a much more limited selection of household essentials than Walmart or Costco, so you might have to stop by one of them on your way home.
Costco Wins on Savings & Bulk Items
According to price comparisons conducted for Consumer Reports, which compared baskets of commonly purchased items at mainstream grocery chains, Costco’s average price was 21.4% lower than Walmart’s, and Trader Joe’s were 24.6% higher than Walmart’s. So overall, Costco is the clear winner if your goal is to save as much as you can.
That said, since Costco sells many of its items in bulk, shopping there makes more financial sense if you’re shopping for a big family or are buying non-perishable items only.
You Don’t Have To Limit Yourself to One
If you live alone and want to save money on everyday essentials like eggs and bread, Walmart is a solid pick. If you don’t mind buying in bulk and want to get the lowest per-unit price, head to Costco. And if you love unique products and flavor combinations that you can't find anywhere else, consider Trader Joe’s.
You don’t have to limit yourself to just one, though. If you live close to all of these retailers, you can always mix and match to maximize your savings and get the most value out of each. Just make sure the savings are actually worth the extra trips.
