Rules to Live By When Shopping at COSTCO (to Save Time, Money, & Sanity)

grocery shopping at costco

Today I did a big grocery haul from Costco, and I thought I would share what I bought. I shop at Costco once a month or so, and I tend to stock up when I go. I’ve also got a few tips on how to stay practical while shopping at Costco, because we all know just how easy it is to lose control and buy all the giant things!

Rules to Live By When Shopping at COSTCO

Rule #1

Bring your regular grocery bags in with you. Plan to buy only what you can fit into your regular bags. You only have so much space in your refrigerator, freezer, and pantry! Plus, if you don’t bring bags, you have to load up in leftover boxes – which you then have to dismantle and recycle at home.

Rule #2

My second rule when grocery shopping at Costco is a tough but important one: GO IN THE GROCERY SECTION ONLY!

Do not let yourself be distracted by the other two-thirds of the store, unless you want to find yourself back home with bags of athletic socks, a new tv, matching beach chairs, a new couch, and more Christmas decorations than you can possibly display, let alone store!

Ok, I’m joking (kinda), but you get the idea.

If you are going for groceries, stick to the groceries. Don’t let the shiny stuff distract you.

Rule #3


That 4-pack of family-sized pizzas is going to look like lunch, so maybe you need two…no, no, no!

Have something to eat before you leave the house or you will overspend and come home with all kinds of crazy things you don’t need, I promise.

If you are coming to Costco at the end of a long morning of errands, at least grab a hot dog or one of those chicken wrap things at the food court before you start shopping.

Ok, I am finished shouting – but those rules are important in order to preserve your sanity and bank account!

What You Should Buy at Costco:

Shop Organic As Much As Possible

Costco does a really good job of sourcing – and labeling – the organic foods they sell.

I am particularly partial to their organic meats. Today I stocked up on chicken breasts and ground beef. I also like their organic ground bison, but didn’t have the bucks to shell out this time around.

The bacon is not organic, but it is a nice, thickly sliced and flavorful bacon.

I separate the packages when I get home and then freeze them all lying flat. They are easier to store that way, and much easier to grab a single package when you are ready to defrost and cook.

Buy Only What You Can Use Up

I was really tempted to grab some salmon, but it was farm-raised (which I avoid) and the cuts were so huge they would go bad before we could finish them – that’s wasted money. Make sure you buy quantities you will finish!

This picture really doesn’t do these items justice. That’s a large bag of oranges on the right, because I like my juice fresh-squeezed.

The tomatoes came in a box of a dozen; we will have no trouble finishing them. They are organic and vine-ripened.

Mushrooms, blueberries, Kerrygold butter (that stuff is divine!).

Like Mexican food? Grab a clamshell package of pre-made chicken street tacos. The only work involved in this meal is to heat the chicken and tortillas, so I save this for one of our busier nights. It beats take-out anytime!

Pantry items include good-quality organic pastas, Dave’s Bread (also organic), Coconut Clusters (my junk food fix), mixed nuts for my husband, and Kirkland’s Maple Syrup.

Costco’s Store Brand, Kirkland, is Good!

In case you are unfamiliar, Kirkland’s is the Costco store brand and the quality of their items is excellent. I usually buy the Kirkland’s coffee, but they only had the dark blend today and we prefer light/medium.

I also stocked up on canned tuna, because we are in earthquake country here and I always like to have an inventory of non-perishables, especially proteins.

Kirkland’s brand extends to alcohol. Today I grabbed a Prosecco, but they do make several reds and whites, and I’ve tried most. They are very good!

I’ve not tried Kirkland’s vodka before, but wow, it was inexpensive, and perfect for when I make this delicious recipe for homemade Kahlua from It’sMySustainableLife. My plan is to give it out as Christmas gifts (I’ll make a little extra for myself!) (Edited to add that I have made the Kahlua several times now and it is delicious! Give it a try!)

Pizza is a Must

It’s almost impossible to go grocery shopping at Costco without grabbing a pizza either at the food court or ready-to-bake. Again, this is an easy dinner for a busy night, and look at all that pepperoni!

All the Smoothie Ingredients

Next we have my three favorite Costco products! Smoothie ingredients for the win.

Most mornings in our house start with homemade smoothies. Even my husband (who has the taste buds of a four-year-old – but don’t tell him I said that!) likes these smoothies.

The bag of power greens can be found in the cold produce room. I toss them in the freezer as soon as I get home, as they seem to blend better when frozen.

I add frozen fruit, and alternate between the Daybreak Blend (peaches, strawberries, mango, and pineapple) and the Three Berry Blend. A little water, some protein powder and beet powder is all that’s needed.

As soon as I got home, I whipped up a fresh smoothie using the Daybreak Blend to drink while I put the groceries away.

Can I just say how much I love my Nutribullet? I think I use it more than any other small kitchen appliance. If you don’t have one – I highly recommend it! My smoothies blend so much more smoothly than those I made in my old blender.

My Non-Grocery Cheat Purchase

I got distracted by the book display and brought home a copy of “The Testaments”.

Yes, I broke my own Rule #2. But Margaret Atwood is my all-time favorite author, and, hello! It’s the sequel to “The Handmaid’s Tale”. I had to have it!

I recognize that everyone shops according to what works best for them, and different families choose to eat, well – differently. And that is as it should be. I hope you enjoyed following along on my trip to Costco today!

    1. It’s amazing the variety in that store, isn’t it? Yes, very easy to just grab the same stuff every time. It’s much easier to explore if you are able to find a less crowded time (and if you do, let me know, ’cause it’s always packed when I go!!!)
