17 Grocery Items That Are So Much Cheaper at Costco

If you've not been indoctrinated into the cult of Costco, you may wonder if it's really all it's cracked up to be. It took a friend in rapture over the price of raw salmon that he bought for sashimi—no, it's not advertised as that, and yes, I do it now, too—to get me into the club store. Like most people who enter the vast wonderland of bulk goods, I immediately saw what all the fuss was about.

My household bought a membership that very day (along with a couple of pounds of salmon) and we've never looked back, even when we traded our big old Victorian with a massive walk-in pantry for a much more streamlined house. I've made it my business to keep an eye on whether things are truly less expensive, even if you're not there to buy vats of mayonnaise. And yes, there's enough stuff there that comes in manageable quantities, even for a household of two, to make it easily worth the $60 annual cost.

I took a spin around my local warehouse in Louisville, Ky., the other day after asking my social media friends about their favorite grocery essentials. I compared the posted prices of these items at Costco with the regular prices at my usual grocery store, Kroger. I did find one thing that (surprise!) wasn't cheaper at Costco. Haas avocados cost $7.39 for a bag of six, or $1.23 apiece. Meanwhile, at Kroger, a four-count bag cost $3.89, or 97 cents each. But for everything else, I found better deals at Costco—in some cases, much better deals.

Here are 17 things that are cheaper at Costco than a regular grocery store:

Harmless Harvest Coconut Water

I could drink a gallon of this pink water a day, but it is bonkers expensive in grocery stores. At Costco, a 6-pack of 14-ounce bottles is $13.89. That's $2.32 a bottle, or 16.5 cents an ounce. At Kroger, it's $4.99 for a 16-ounce bottle, or 31 cents per ounce. Yes, basically double! Look, even if I only drank one bottle a week, this one thing alone would pay for the membership—almost twice.
