A new study compares the use-by dates shown on items ordered online from different supermarkets, finding variation in how long products are typically dated for after purchase. The report focuses specifically on the shortest and longest use-by dates available through online ordering.

The outlets describe the study’s findings as a measure of shelf life being offered to online shoppers, based on the dates attached to products at the time of order. While the available coverage does not provide further methodological detail or specific rankings in the provided text, the shared emphasis is on identifying which retailers present the most immediate “use-by” deadlines versus those offering longer remaining time.

Overall, the coverage aligns on the central point: supermarkets differ in the remaining use-by time displayed for online orders, and the study highlights those differences to help consumers understand the potential freshness window for items bought remotely.
