I work at Costco and spend $100 a week there to feed my family of 4. Here are 10 things we love to buy.

Kirkland Signature’s 40-pack of water lasts us a while.

If you buy bottled water, a pack from Kirkland Signature is the way to go. The labels on each recyclable bottle even have a place to write a name, which is great when dividing water among kids and adults at gatherings.

I think it has a great refreshing taste at only $4.99 for a pack of 40 bottles.

Crazy Cuizine’s Mandarin orange chicken is delicious.

Crazy Cuizine’s Mandarin orange chicken is a family favorite on our menu twice a month. Each pack contains delicious lightly battered chicken breast and rib meat and a sweet and tangy orange sauce.

This meal is great for a quick and easy dinner in less than 20 minutes.

Each box contains 4 pounds of chicken with two packets of orange sauce for $13.99.

I always restock on bananas at Costco.

My kids love bananas so we go through them pretty fast. Whether they’re eaten as a snack, sliced on top of pancakes, or used for banana bread, we need this fruit in our house.

Costco offers a great deal of 3 pounds for $1.99.

Mission’s Carb Balance tortillas are great for tacos and wraps.

Mission’s Carb Balance tortillas are one of my favorite products and are versatile enough for mini pizzas, wraps, and countless other meals.

I can also feel guilt-free about treating myself to these because they only contain 4 grams of net carbs and 0 grams of sugar per serving.

Costco sells Mission’s delicious 16-count tortillas for $6.79

The Krusteaz buttermilk-pancake mix is a breakfast staple for weekends.

Pancakes are a must for my family every Saturday. With the Krusteaz buttermilk mix, all I have to do is add water to get light and fluffy pancakes that meet every expectation.

You can also use this mix to make waffles.

I grab a 10-pound bag of the Krusteaz buttermilk-pancake mix for $7.99.

Dave’s Killer Bread is so flavorful.

I think Dave’s Killer Bread is on another level because it’s packed with protein, fiber, and grains.

Its subtly sweet flavor, hearty texture, and seeded crust that will take your sandwich from boring to delicious.

It can be a little pricey if you purchase it at the grocery store, but Costco sells two 27-ounce loaves for $9.59.

On busy mornings, I reach for Lunchables.

When I don’t have time to make lunch for my kids, Lunchables come in handy.

I typically buy the version that comes with turkey, cheddar cheese, crackers, and some mini candy.

You can get a six-pack for $9.49 at Costco, less than the $1.60-per-pack price tag I’ve seen at other stores.

Kirkland Signature’s stir-fry veggies are a family favorite.

Kirkland Signature’s stir-fry veggies are a must for our family at least five days a week. We love to meal prep our lunches and this tasty blend of frozen veggies is so quick and easy.

Each blend contains broccoli, mushrooms, onions, green beans, peas, carrots, and red and yellow peppers. My family loves when I prepare this blend with chicken and rice.

You can grab a 5 1/2-pound bag for $11.49.

Kirkland Signature’s organic applesauce is a no-brainer.

My kids are always snacking so I like to stock up on a 24-pack of Kirkland Signature’s organic applesauce.

This no-mess grab-and-go snack is made with USDA organic apples and has no added sugar.

I like to refrigerate them or just toss them in the cabinet. A pack of 24 pouches retails for $10.99.

I think Kirkland Signature’s chicken breasts are a great deal.

Our main source of protein is chicken, so buying in bulk is a must. Costco offers individually sealed packs of chicken breast, making it convenient if you need to freeze some.

I love to bake chicken in a casserole or use it for a slow-cooker recipe with some veggies and potatoes.

Kirkland Signature’s chicken breast retails for $3.49 per pound.
