French supermarkets run on a set of small, unwritten rules that catch self-catering visitors off guard more than the food itself.
None of them are hard to learn, but skipping them turns a five-minute grocery run into a confusing one.
Key takeaways
France banned single-use plastic bags at checkout on July 1, 2016, so bring your own bag or buy a reusable one at the register. Loose produce usually needs to be weighed and stickered yourself before checkout. Milk and eggs are often shelved unrefrigerated, which isn't a storage mistake, it's standard French practice.
Do I need to bring my own bags to a French supermarket?
Yes, in practice. France banned single-use plastic bags at checkout starting July 1, 2016, under the country's Energy Transition and Green Growth law, and cashiers will ask "Vous avez un sac?" (do you have a bag?) rather than automatically bagging your groceries (France 24, Plastic Shopping Bags in France Are Now History, retrieved 2026-09-12). Reusable bags (sacs cabas) cost roughly €0.10-0.20 at most registers if you forget one.
Bringing a foldable bag from home saves more than the small purchase cost. It also skips the moment of fumbling for change at checkout while a line forms behind you, which is a bigger deal in France's smaller supermarket footprints than it sounds.
Why do I have to weigh my own fruit and vegetables?
Most French supermarkets require you to weigh and sticker loose produce yourself before reaching the checkout, using small scales positioned directly in the produce section. You select the item on a touchscreen, print the price sticker, and attach it to your bag; skipping this step means the cashier has to send you back to do it, which slows down the whole line.
The touchscreens are usually available in English as a language option, so the process is faster than it looks the first time. Look for a small flag icon in the corner of the screen.
| Habit | What to expect | Why |
|---|---|---|
| Bagging | Bring your own or buy one at checkout | Plastic bags banned since July 2016 |
| Loose produce | Weigh and sticker it yourself | Speeds up checkout lines |
| Milk | Often unrefrigerated (UHT) | Standard French processing, not spoiled |
| Eggs | Often unrefrigerated on shelves | Different washing/storage standards than the US |
| Checkout divider | Place it behind your items, not before | Signals where your order ends |
Why are milk and eggs sitting on a regular shelf, not refrigerated?
Because most French milk is UHT (ultra-pasteurized), which is shelf-stable until opened, and eggs are commonly sold unrefrigerated due to different washing standards than in countries like the US. Neither is a sign of spoiled or mishandled food; both practices are standard across French supermarkets, from small city Monoprix locations to large suburban Carrefour stores.
What should I know about checkout etiquette specifically?
Place a small divider stick (séparateur) behind your groceries on the belt, not in front of them, to mark where your order ends and the next customer's begins. Loading heavier items first makes bagging easier once you reach the end of the belt, since French checkouts move quickly and there's often limited counter space to sort items afterward.
