Grocery bills keep rising, but changing what you eat is not always realistic. You can still lower your total by adjusting how you shop, not what you buy.

ChatGPT offered several practical ways to cut costs while sticking to your regular grocery list.

Track Unit Prices Instead of Shelf Prices

ChatGPT suggested using unit prices, such as cost per ounce or pound, as a more reliable way to compare prices than shelf prices alone. Unit pricing gives you a consistent baseline, especially when brands, sizes or promotions differ, the artificial intelligence (AI) explained.

One place this strategy matters most is when choosing between package sizes. Bigger is not always cheaper. Stores sometimes discount smaller options, which can bring the per-unit cost below the larger package you normally grab.

Also compare the price of value packs with individual items. In some cases, buying the same number of items separately costs less than the bundled version.

Rotate Stores Based on Price Strengths

No store has the best prices in every category. ChatGPT explained that one store may price meat lower while another consistently has better prices on dairy or pantry staples. It added that shopping two stores for the same list can cut 10% to 20% off a weekly bill.

To make comparing prices easier, use an app, like the newly launched Grocery Dealz, which is like Gas Buddy for groceries according to one of its co-founders.

Time Purchases Around Sales Cycles

Most grocery stores run predictable eight- to 12-week sale cycles, said ChatGPT. If you buy the same items regularly, it suggested stocking up when prices drop and avoiding paying full price the rest of the time.

Once a price drops, expect it to rise and then come back down within two to three months.

Use Store Apps for Automatic Savings

Use store apps to find and clip digital coupons for items you already buy, said ChatGPT. It also noted that store apps can unlock member-only pricing that does not require changing brands or quantities.

However, it’s still important to check unit prices and other stores to make sure you’re getting the best deal. 

Switch From Weekly to Biweekly Stock-Ups

Impulse buying accounts for 62% of grocery store revenue, according to Capital One Shopping.

Buying the same items every two weeks instead of weekly can reduce impulse purchases, said ChatGPT.

Pay Attention to Store-Brand Equivalents You Already Buy

If you already rotate between brands, store-brand versions are often comparable in quality and are sometimes produced by the same manufacturers as name-brand items, according to ChatGPT. Choosing store brands can lower the cost of each item by about 15%-25%.
