Discount grocers like Aldi and Lidl promise much lower prices. We break down where the savings are real, where they disappear, and how to shop both worlds.
If you've ever walked into a discount grocery store and noticed that your usual brand of pasta sauce costs half as much, you've felt the pull. Stores like Aldi and Lidl have built their reputations on low prices, and groceries are one of the few budget categories where a small change in habits adds up every single week.
But does switching actually save money, or does it just move your spending around? Let's look at how discount grocers keep prices low, where they shine, where they don't, and how to build a shopping routine that gets you the best of both.
A discount grocer isn't magic. It simply cuts costs in ways you can see (and sometimes feel) while shopping.
Most of their stock is store-brand products rather than national brands. A private-label cereal costs less to make and market than a big-name one, and the savings get passed along.
They carry fewer items. A typical supermarket might stock tens of thousands of products. A discount store may stock only a fraction of that, which means simpler shipping, faster restocking, and fewer employees needed to manage shelves.
They cut service costs. Many ask you to bring your own bags, bag your own groceries, or return a cart for a small deposit. Products often stay in the shipping boxes they came in. Fewer employees stocking shelves means lower overhead.
The overall effect is that your cart total tends to drop noticeably for similar staples. Estimates vary by region and basket, but savings of 20% or more on comparable items are commonly reported by shoppers and comparison studies. Your own results depend on what you buy and what's near you.
Discount stores are strongest on everyday staples: milk, eggs, bread, butter, canned goods, frozen vegetables, pasta, rice, cheese, and basic produce. Many shoppers find the store-brand quality perfectly good for these items, and in blind taste tests plenty of private-label products hold their own.
They're also good for limited-time specialty items, such as seasonal foods or imported snacks, though those rotate and sell out.
If you want to compare more broadly, our guides on warehouse club math and grocery delivery versus curbside pickup look at two other ways to trim the bill.
There are real trade-offs, and it's worth being honest about them.
Brand loyalty costs more. If your family insists on one specific brand of peanut butter or dish soap, the discount store may not stock it. You'll either switch or make a second trip.
Selection gaps. Specialty diets, ethnic ingredients, and certain produce or meat cuts may be harder to find. You may need a second store for those.
Time and convenience. Bagging your own groceries and a smaller layout are fine if you're used to it. But if you're hauling kids or a long list, the time cost is real. A store that's 20 minutes out of your way may cost more in gas and time than it saves.
The impulse-buy aisle. Many discount grocers have a rotating aisle of non-food items, from kitchen gadgets to garden tools. They're tempting, and they're not groceries. Stick to the list.
Also be careful about unit pricing. That's the price per ounce, pound, or count, shown on the shelf tag. A bigger package at a traditional store sometimes beats the discount store's smaller package once you compare unit prices. Building a habit of checking this is worth the effort, and our walk-through on how to build a grocery price book shows you how.
Meet Maya and Tom, a family of four who spend about $210 a week at a traditional supermarket on their usual basket: milk, eggs, bread, chicken, vegetables, pasta, cereal, snacks, and a few household items.
Maya prices the same list at a nearby discount grocer over a few weeks. Here's what she finds.
About 80% of the list (the staples) costs around $135 there.
The remaining 20%, including Tom's preferred coffee, a specific brand of gluten-free pasta, and a few cleaning products, isn't available or costs more. She still has to buy those at the regular supermarket for about $35.
New weekly total: $135 plus $35 equals $170, compared with $210 before. That's $40 less per week.
Over a year (call it 50 weeks), that's $2,000 in savings. But Maya subtracts some real costs. The discount store is a 10-minute detour, adding roughly $6 of gas each week ($300 a year), and she occasionally loses to the impulse aisle, which she estimates at $15 a month ($180 a year).
Her net savings: $2,000 minus $300 minus $180, or about $1,520 a year. That's still a meaningful number, and it's real because she tested it with her own list instead of relying on a headline percentage. If she moved the odd-brand items to a store brand, she'd save more.
The lesson: savings are real, but they're yours only if you price your own cart.
The first mistake is going in without a list. Discount stores are designed for focused trips. Wandering turns a $60 stop into a $110 stop.
The second is assuming everything is cheaper. Some items, especially national-brand products on sale at the traditional supermarket, may win on price. Keep an eye on the weekly flyers.
The third is forgetting to count the extra trip. If you split your shopping between two stores, factor in gas and time. For many families the savings still win, but not always.
The fourth is buying more just because it's cheap. Food waste cancels out savings fast. A few perishable items you throw away can erase a week of gains. Pairing a discount shopping habit with a plan, such as the approach in our guide to meal prepping to cut your grocery bill, helps keep waste down.
The fifth is skipping the payment side. If you're buying groceries on a card anyway, a card with a strong grocery category can add to your savings. Compare options on our cash back cards page, but only if you pay the balance in full each month, since interest would swamp any rewards.
Pick your 25 most-bought items and write down what you pay today.
Price them at a nearby discount grocer using the shelf tags or the store's online flyer.
Compare unit prices, not just sticker prices.
Switch the staples that pass the taste test, and keep the brands you truly care about where they're cheapest.
Track your grocery spending for a month and see how much it changed.
If you want to automate the tracking, plenty of budgeting apps can categorize grocery spending for you, though the old-fashioned notebook works just as well.
Discount grocers like Aldi and Lidl can cut a real chunk out of a typical grocery bill, especially if you're flexible on brands and willing to shop with a list. The savings aren't automatic, though. Price your own basket, count the extra trip, and keep the traditional supermarket for the items where it wins. A hybrid routine is often the sweet spot.
