We checked 270 products on Google's two shopping screens. 80 had two different prices.

About the prices in this post. Every price here is what we recorded on September 7, 2026. Prices move constantly, and that turns out to be a big part of the story. Some of these will already have changed by the time you read this.

If you have shopped on Google lately, you have probably noticed it answering you directly in a tab called AI Mode instead of just handing you a list of links. It names a product and quotes you a price.

We wanted to know one narrow, practical thing: how reliable is that price?

So we asked Google 240 ordinary shopping questions, the kind anyone types in. Then we took every product that turned up in both AI Mode and Google's own Shopping tab on the same day, and compared the two prices for the same item.

Most of the time, the price matches

Start with the good news, because it is most of the answer.

We found 270 products that appeared on both screens the same day. Each one is matched by Google's own product identifier and confirmed by checking that the star rating and review count agree on both. 190 of them were priced exactly the same. Ask about a 65 inch OLED TV and AI Mode quoted an LG C5 at $1,499.99. The Shopping tab had the same TV at $1,499.99, to the penny.

So about 7 times in 10, the price you are quoted is the price.

The other times

80 of those products carried two different prices on the same day. When the two disagreed, the AI Mode figure was the higher one 60% of the time.

The gap was lopsided too. When AI Mode was the more expensive of the two, the difference ran a median of 20.2%. When it was the cheaper one, the difference was a median of -8.3%. A disagreement costs you more than twice as much when it goes the expensive way.

Four we caught on camera

We screenshotted both screens minutes apart on September 7, 2026. In each pair it is the same product, confirmed by the matching star rating and review count.

Why this happens

This part matters, because it is not a conspiracy and we are not going to pretend it is one.

Prices change many times a day. Different stores run different promotions, and they start and end at different hours. A product that is stocked by a dozen sellers has a dozen prices at any given moment, and they do not move together.

Any single answer is a snapshot of one moment and one seller. Google is quoting a real price from a real store. It is just not always the lowest one available for that product right then, and a snapshot can go stale between the time it is taken and the time you read it.

That is true of every single source, and it is true of us too. One price is one data point. The fix is not to distrust any particular one. The fix is to look at more than one.

What the same product cost when we checked

That is the whole job at ShopSavvy, so we ran the same products through our own price check the same day. We show every seller we can find and sort by price, always. Nobody can pay us to sit above anyone else.

Here is what the comparison looked like on September 7, 2026.

Across those 9 items, the lowest price we found came to $295.86 less in total than the AI Mode figure, an average of $32.87 per item.

Read that as an illustration, not a league table. We picked products where we could put a current price on all three screens at once. On 5 of the 9 we came in under Google Shopping's own price as well, and on the rest we matched it. Google Shopping is a price comparison tool too, and a good one.

What you can do about it

Nothing here says do not use AI Mode. It is fast and it is often right, and seven times in ten the price it gives you is the same price you would find anyway.

It says the number is worth a second look before you spend real money.

Check a second price before you buy, especially on anything expensive. The Shopping tab is one click away and it will usually show you a range.

Look for the same product rather than a similar one. Star ratings and review counts are the easiest way to tell two listings are really the same item.

And if you would rather not do that by hand, that is what we built. ShopSavvy checks thousands of stores and sorts by price.

How we did this

We wrote 240 shopping questions across 12 categories, phrased the way people actually browse rather than the way you search for a model you have already chosen. We ran each one through Google AI Mode and through the Google Shopping tab on September 7, 2026, from a United States English session, and recorded what each returned.

To compare the same product across two screens we used Google's own product identifier, then confirmed the match by checking that the star rating and review count agreed on both. Titles alone are not enough. The same keyboard is "Apex 9 Gaming Keyboard" on one screen and "SteelSeries Apex 9 TKL Gaming Keyboard" on the other.

What we are not claiming

Being straight about the limits makes the rest more believable, so here they are.

We are not making any claim about which products get recommended. That is an editorial judgement and this study did not test it. Everything above compares prices for products both screens already showed.

We measured what happened, not why. Nothing here shows intent, and we did not find evidence of any.

This is one day of data: September 7, 2026, United States, English. That is a snapshot of a surface Google is actively changing.

These gaps move. We re-ran eleven examples from an earlier study by another team, and only three could still be measured a week later. One gap had closed completely, one reproduced exactly, and one had reversed. A single screenshot shows that these differences happen. It does not show that any particular product is always more expensive.

Check it for yourself

You do not have to take our word for any of this. Pick a product from the table, search that question on Google, and look at the Shopping tab and AI Mode side by side. It takes about a minute.

If the prices have moved since September 7, 2026, that is worth knowing too. Tell us what you find.
