Shoppers often pay as much attention to the expiry date on a product as they do to the price - especially if it means your milk will be good for an extra day or two.
But while the food itself may only last a few days after you buy it, there are new stickers appearing with dates hundreds of years in the future.
Why? It's a plan from Gagandeep Jhuti and Joe Foale-Groves to raise awareness of just how long the packaging your food comes wrapped in will last, Manchester Evening News reports.
The pair, who work in advertising, created Plastic Expiry Date stickers for single-use meal deal packaging, and now they have started to appear on some supermarket items in the UK.
The idea was to help raise awareness among shoppers about how their daily meal deals add up to affect the planet.
Over a thousand stickers have appeared on products in supermarkets around London, but they've also been spotted around the UK as eco-friendly shoppers try to help spread the message.
Speaking to Manchester Evening News, Gags and Joe explained how their idea came about.
They said: "So imagine this. It’s the year 3019. Animals can now be tried in court. The prisons are overflowing with pigeons. You are no longer around.
"But the plastic water bottle you bought with your meal dea in 2020 has finally started to decompose. Even if the future isn’t quite as weird as that, it is true that your meal deal could be pretty much immortal."
And the endgame?
"The ultimate goal would be for supermarkets to add the Plastic Expiry Date to packaging themselves, as well as hurrying to remove single-use plastic packaging from their shelves."
