Why I Grocery Shop at 3 Different Stores (And Still Save Time)

“Just shop at one store. It’s easier.”

That’s what everyone told me. One weekly trip. One shopping list. One cart. One checkout line. Simple.

So I tried it. For a month, I did all my grocery shopping at one store. I made comprehensive lists. I planned my route through the aisles. I consolidated everything into one trip.

And you know what? It took longer. It cost more. And it was more stressful.

Then I tried something counterintuitive: shopping at three different stores strategically. And it changed everything.

The One-Store Trap

Here’s what happened when I tried to shop at one store:

Longer Lists = More Wandering

When you’re shopping for everything at once, your list gets long. Really long. And long lists mean more wandering, more backtracking, more decision fatigue.

I’d start in produce, realize I forgot something in dairy, backtrack to dairy, then realize I needed something from the other end of the store. I was zigzagging through aisles, wasting time.

Decision Fatigue

By the time I got to the end of my list, I was exhausted. I’d grab whatever looked easiest, not what was best. I’d skip price comparisons because I was too tired to think. I’d make impulse purchases because I just wanted to be done.

Higher Costs

One-store shopping meant I was buying everything at regular grocery store prices. No bulk discounts. No Aldi savings. No Costco deals. I was paying premium prices for convenience that wasn’t actually convenient.

More Stress

The long list. The crowded store. The wandering. The decision fatigue. By the time I got home, I was exhausted and stressed. Not exactly the peaceful shopping experience I was promised.

My Three-Store System

After tracking my time and spending for a month, I realized: shopping at multiple stores strategically isn’t chaotic. It’s efficient.

Here’s my system:

Store 1: Costco (Monthly)

When: Once a month, usually the first Saturday Time: 30 minutes What I buy: Bulk staples only

  • Meat (chicken breast, ground beef—I portion and freeze)
  • Paper products (toilet paper, paper towels)
  • Canned goods (tomatoes, beans)
  • Oils and vinegars
  • Rice and pasta (if I’m running low)
  • Frozen vegetables (big bags)

Why it works: Costco is for staples I know I’ll use. I don’t browse. I don’t impulse buy. I have a list, I stick to it, I get out.

Time investment: 30 minutes monthly = 7.5 minutes per week

Store 2: Aldi (Weekly)

When: Once a week, usually Tuesday or Wednesday morning Time: 20 minutes What I buy: Produce and weekly basics

  • Fresh produce (fruits and vegetables)
  • Milk and eggs
  • Bread
  • Cheese
  • Snacks
  • Anything else on my weekly list that’s not a bulk item

Why it works: Aldi is small and efficient. I know the layout. I can get in and out quickly. The prices are great, and the quality is good enough for most things.

Time investment: 20 minutes weekly

Store 3: Regular Grocery Store (As Needed)

When: Quick trips for specific items Time: 15 minutes per trip What I buy: Specific items I can’t get elsewhere

  • Specific brands my family prefers
  • Ingredients for new recipes
  • Items Aldi doesn’t carry
  • Last-minute needs

Why it works: I’m not doing a full shop here. I’m in and out. I know exactly what I need, I grab it, I leave.

Time investment: 15 minutes, 1-2 times per week = 15-30 minutes weekly

The Master Shopping List Organized by Store

Here’s how I organize my shopping:

Costco List (Monthly)

  • Chicken breast (bulk)
  • Ground beef (bulk)
  • Canned tomatoes (bulk)
  • Canned beans (bulk)
  • Rice (if needed)
  • Pasta (if needed)
  • Olive oil
  • Toilet paper
  • Paper towels
  • Frozen vegetables (bulk)

Aldi List (Weekly)

  • Produce (fruits and vegetables)
  • Milk
  • Eggs
  • Bread
  • Cheese
  • Yogurt
  • Snacks
  • Other weekly needs

Regular Grocery Store List (As Needed)

  • Specific brand items
  • Recipe-specific ingredients
  • Items Aldi doesn’t carry

Having separate lists helps me stay focused. I’m not wandering. I’m not impulse buying. I’m just getting what I need from each store.

How This Actually Saves 2-3 Hours Per Month

Let me break down the math:

One-Store Shopping (What I Used to Do)

  • One weekly trip: 90 minutes (including travel, shopping, checkout, unloading)
  • Monthly total: 360 minutes (6 hours)

Three-Store Shopping (What I Do Now)

  • Costco monthly: 30 minutes
  • Aldi weekly: 20 minutes × 4 = 80 minutes
  • Regular grocery (as needed): 15 minutes × 6 = 90 minutes (2-3 trips per month)
  • Monthly total: 200 minutes (3.3 hours)

Time saved: 160 minutes (2.7 hours) per month

Plus, I’m saving money. Aldi prices are significantly lower than regular grocery stores. Costco bulk prices save money on staples. I’m not impulse buying because I’m not wandering through aisles.

When This Doesn’t Work (And What to Do Instead)

This system works for me, but it might not work for everyone. Here’s when you might need a different approach:

If You Don’t Have Multiple Stores Nearby

If you live in a rural area or don’t have Costco/Aldi nearby, this system won’t work. In that case, focus on:

  • Efficient one-store shopping (organized list, strategic route)
  • Online grocery ordering (if available)
  • Meal planning to reduce trips

If You Have Very Young Children

Shopping with multiple kids can be exhausting. In that case:

  • Do Costco trips alone (during nap time or with a partner)
  • Use Aldi pickup or delivery if available
  • Minimize trips to regular grocery stores

If You Prefer One-Store Shopping

If you genuinely prefer one-store shopping and it works for you, keep doing it! The goal isn’t to change your system—it’s to optimize whatever system you use.

PERSONAL QUOTE PLACEHOLDER: “[Insert your own quote here, something like: ‘I know multi-store shopping sounds complicated, but for me, it’s actually simpler. Each store has a purpose, and I’m not wasting time wandering.’]”

The Key Principles

Whether you shop at one store or three, here are the principles that make shopping efficient:

1. Know Your Stores

Understand the layout. Know where things are. Don’t wander.

2. Have a List

Organize your list by store (or by aisle if you’re doing one-store shopping). Stick to it.

3. Shop Strategically

  • Buy bulk items in bulk (but only if you’ll use them)
  • Buy fresh items weekly (but only what you need)
  • Buy specific items as needed (but don’t make extra trips)

4. Time Your Trips

Shop when stores are less crowded. For me, that’s Tuesday/Wednesday mornings. For you, it might be different.

5. Don’t Browse

Get in, get what you need, get out. Browsing leads to impulse buying and wasted time.

The Real Benefits

Beyond time and money savings, here’s what I’ve gained:

Less Stress

I’m not wandering. I’m not overwhelmed. I’m just getting what I need, efficiently.

Better Organization

Separate lists for separate stores help me stay organized. I know exactly what to get where.

More Flexibility

If I need something specific, I can grab it quickly. I’m not locked into a weekly mega-trip.

Reduced Food Waste

Buying weekly produce means it’s fresher when I buy it and gets used before it goes bad. Buying bulk staples means I always have basics on hand.

Making It Work for You

If you want to try multi-store shopping, here’s how to start:

  1. Identify your stores: What stores do you have access to? What are their strengths?
  2. Create separate lists: Organize your shopping list by store
  3. Start small: Try it for a week. Track your time and spending
  4. Adjust as needed: What works? What doesn’t? Adjust your system

Remember: the goal isn’t to shop at multiple stores. The goal is to shop efficiently, whatever that looks like for you.
