10 Things That Shock Brits When They Visit an American Supermarket

Walking into an American supermarket for the first time can feel like stepping onto another planet. Everything is bigger, louder, and packed with choices you never even knew existed. From massive milk containers to entire aisles dedicated to just one type of food, there’s a lot that can catch a Brit off guard. If you’ve ever been to Tesco or Sainsbury’s, you might think you know what to expect, but trust us—American supermarkets are a whole different experience. Here are ten things that Brits find completely shocking when they visit a grocery store in the US.

1. Milk Comes in Gallons, Not Pints

Why does anyone need that much milk? Seriously. In the UK, the biggest bottle you’ll usually buy is a four-pinter, and even that feels like a lot. But in the US, milk is sold in gallon jugs—almost four times the size of a standard UK pint.

It’s not just the size that’s surprising; it’s how normal it is. Americans casually grab these massive jugs like it’s no big deal. You start wondering—are they making tea for an entire village? Do they have a family of ten? But no, even single people seem to buy milk in these huge containers.

It turns out that American fridges are built for bulk shopping, and milk is a staple in many households. Since they use it for everything—from drinking to cooking to pouring over their endless bowls of cereal—it makes sense to buy in large amounts. Plus, milk in the US has a longer shelf life than in the UK because of how it’s processed.

Still, for a Brit, hauling a gallon of milk to the checkout feels ridiculous. You suddenly miss your sensible little two-pint bottle back home.

2. Aisles Dedicated to Just One Thing

A whole aisle just for cereal? An entire wall of peanut butter? It’s overwhelming.

In the UK, supermarkets have a reasonable selection of things like cereal, crisps, and biscuits. You get a few choices, maybe a special “family size” box, and that’s it. But in the US, the variety is on another level. You don’t just get one section for cereal—you get an entire aisle, packed floor to ceiling with every brand, flavor, and sugar-loaded version imaginable.

Peanut butter? Same story. You’ll see rows of different brands, types (crunchy, smooth, extra smooth, organic, sugar-free), and even different flavors. It feels like too many choices for something as simple as peanut butter.

For Brits, this much variety can be a bit much. You come in expecting to grab a quick snack and end up standing there for ten minutes, trying to figure out if you want “Honey Nut Frosted Flakes” or “Cinnamon Toast Crunch with Marshmallows.” It’s a lot to process.

3. 50 Different Kinds of Oreos

Back home, you have original and maybe double-stuffed. That’s it. But in the US? There are more flavors of Oreos than you ever thought possible.

Birthday cake, peanut butter, mint, cinnamon bun, caramel coconut, even ones that taste like fireworks (yes, really). It’s like every time you blink, a new Oreo flavor appears. There are seasonal ones, limited edition ones, and ones that make you wonder why anyone thought they were a good idea (looking at you, Swedish Fish Oreos).

At first, it’s exciting. You think, “Wow, I need to try all of these!” But then you realize that you could buy a different kind of Oreo every week for a year and still not get through them all.

It makes you wonder—do Americans even eat normal Oreos anymore, or are they constantly chasing the next weird flavor?

4. Bread Is Weirdly Sweet

Even “regular” sandwich bread tastes like cake.

You pick up a loaf that looks normal, but the moment you take a bite, something feels off. It’s soft—too soft—and there’s an unmistakable sweetness that doesn’t belong in a ham sandwich. Some brands are so sugary they might as well be brioche.

In the UK, bread is just bread. It’s flour, water, yeast, and salt—simple and straightforward. But in the US, many brands add sugar or corn syrup to their recipes. This makes the bread last longer, but it also means that even a basic cheese sandwich tastes a little bit like dessert.

Finding bread that isn’t sweet can be a challenge. Some Brits hunt down “European-style” loaves or stick to sourdough just to get something that feels normal. But if you’re used to UK-style bread, American supermarket loaves will always taste a little strange.

5. Eggs Aren’t Refrigerated

In the UK, eggs are stored on shelves at room temperature. Seeing them in the fridge section in the US is unsettling.

At first, you might think, “Wait, is there something wrong with American eggs?” But actually, it’s all down to how they’re processed. In the US, eggs are washed to remove bacteria, but this also strips away a natural protective coating. Without that, they need to be kept cold to stay fresh.

In the UK and most of Europe, eggs aren’t washed, so they can safely sit on a shelf without refrigeration. It’s just a different way of handling food safety.

Even though there’s a good reason for it, seeing chilled eggs can catch you off guard. It just feels wrong to have them sitting next to the milk instead of in a regular dry aisle.

6. Checkout Baggers Are a Thing

Having someone bag your groceries for you? Feels like VIP treatment.

In the UK, you bag your own shopping. You scan your items, pick up your bags, and get on with it. But in the US, there’s usually someone waiting at the end of the checkout to do it for you.

At first, it’s a bit awkward. Do you help? Do you just stand there? It feels odd to have someone else handling your groceries while you just watch. But after a couple of trips, you start to appreciate it. It’s actually pretty nice not having to rush to pack everything before the next person’s groceries come flying down the belt.

Some people even take it to the next level and tip the baggers. That’s when you really feel out of your depth—do you tip? How much? Nobody teaches you this stuff before you visit.

7. The Frozen Food Aisle Is Insanely Large

You could live off frozen meals alone, and many Americans do.

In the UK, the frozen food section is usually just a few aisles. There’s some ice cream, a few pizzas, maybe some frozen chips, and that’s about it. But in the US, the frozen food section is massive.

There are entire aisles dedicated to frozen breakfast food, frozen snacks, frozen vegetables, and frozen versions of meals you never even thought could be frozen. You start to wonder—do Americans even cook, or do they just live off microwave meals?

8. Supermarkets Sell Everything

Need a shotgun, a gallon of ranch dressing, and a prescription refill? All in one place.

In the UK, supermarkets sell food. Maybe some clothes, maybe some electronics, but that’s about it. In the US, you can walk into a supermarket and buy everything from furniture to firearms.

It’s slightly terrifying but also kind of impressive.

9. Massive Portions Everywhere

Even pre-packaged food comes in “family size,” but it’s really just American size.

You buy a “regular” Coke and it’s nearly double the size of the one you get back home. A bag of crisps? Feels like it’s meant for a party, but it’s just a normal snack size in the US.

Everything is bigger here. No wonder American fridges need to be massive.

10. So Many Flavors of Soda

Mountain Dew alone has more flavors than most Brits knew existed.

Forget Coke, Diet Coke, and maybe one or two other options. In the US, the soda aisle is huge, with flavors you didn’t even know were possible. Some of them are amazing, others are just confusing.

It’s a lot to take in, but if you love fizzy drinks, it’s also kind of exciting.
