Are store brands always cheaper? A local comparison of store-brand and discounted name-brand basket totals using current weekly offers in each supported city.

No. A discounted name-brand product can undercut a store-brand equivalent during the weekly offer period, so the cheaper basket depends on your list, location, pack sizes, and the offers available when you shop.

Start with the same basket

A fair comparison begins with a fixed shopping list. If the store-brand basket contains 500 g of pasta while the name-brand basket contains 1 kg, the lower shelf price tells you little.

Write down the product, quantity, and any requirements that matter. A practical comparison list might include:

• 1 litre of milk
• 500 g of pasta
• 500 g of ground coffee
• 1 kg of rice
• 400 to 500 g of breakfast cereal
• 1 bottle of laundry detergent, with the number of wash loads recorded

Keep acceptable substitutions clear. If you will buy either whole or semi-skimmed milk, say so. If a specific detergent is required because of allergies, it cannot be replaced merely because another product costs less.

This prerequisite matters because a cheap basket with missing or unsuitable items is not a useful result. The two missing matches in an Aldi basket shows why incomplete coverage can make a total look better than it really is.

Compare unit prices before shelf prices

Store brands often have a lower regular shelf price. Weekly promotions can reverse that order, especially when the name-brand pack is larger.

Compare equivalent units:

• Price per kilogram for rice, pasta, cereal, and coffee
• Price per litre for milk, juice, and cleaning liquids
• Price per wash for laundry detergent
• Price per item for products sold in multipacks

Suppose a store-brand package costs less at the shelf but contains fewer servings. The name-brand offer may deliver the lower unit price, even though its checkout price is higher. The right choice depends on whether you will use the extra quantity and whether the larger purchase fits this week’s budget.

Watch for multi-buy conditions too. “Two for less” only helps when you need two. Buying an extra package to unlock a discount raises today’s basket total and may shift money away from other items.

Run the comparison locally

Weekly offers vary by retailer, market, and location. A result from Cologne cannot settle the same question in Munich, Madrid, Dallas, or Atlanta. Even two branches of the same retailer may not provide an identical set of relevant offers.

For every supported city, use the same process:

1. Set the correct country market so prices appear in the local currency and units.
2. Choose your location or shopping radius.
3. Enter the fixed list with quantities.
4. Record the cheapest suitable store-brand match for each item.
5. Record any discounted name-brand match with an equal or lower unit price.
6. Compare the completed basket totals.
7. Repeat after the weekly offers change.

Best Price Alert compares current weekly and catalogue offers from nearby retailers across supported markets in Germany, Spain, and the United States, with French coverage expanding. The useful output is local and time-specific. It should identify the products included, unmatched items, total basket cost, store locations, and travel distance.

Do not turn one week’s result into a permanent rule. A name-brand cereal might win this week, then return to its regular price while the store brand stays stable.

Build three totals

A two-column comparison can hide the most practical choice. Calculate three baskets instead:

• An all-store-brand basket using the cheapest suitable store-brand option for every item
• A discounted-name-brand basket using name brands only where a current offer applies
• A mixed basket choosing the lower comparable price item by item

The mixed basket will often be the strongest candidate because it avoids brand loyalty in either direction. Store-brand milk may remain cheaper while a promoted name-brand coffee or detergent wins on unit price.

Keep unavailable products visible. If the name-brand basket covers eight of ten items, its subtotal cannot be compared directly with a complete store-brand basket. Price the missing items separately or mark that basket incomplete.

Add travel before choosing the winner

The lowest product total can require another stop. That creates a real tradeoff: fuel, transit fare, walking distance, parking, and time.

Compare at least two plans:

• The cheapest complete one-store basket
• The cheapest complete multi-store basket, usually capped at two stores first

Then look at the difference. A second stop that saves a small amount may be poor value when it adds a long detour. A nearby second store may make sense when it cuts the total enough to matter to your household.

Use your own preference rather than a universal threshold. Someone already passing both stores has a different calculation from someone making a separate drive. For a fuller decision method, see when a second grocery stop justifies the savings.

Repeat the check when offers change

Save the list so the next comparison starts with the same quantities and requirements. Re-run it after new weekly offers appear, then watch the few products that regularly change the basket total, such as coffee, detergent, cereal, meat, or personal-care items.

Your next action is simple: choose ten products you expect to buy this week, record their required sizes, and compare the complete store-brand, promoted name-brand, and mixed baskets within your normal shopping radius.
