Bank holidays are M&S’s wildcard. Monday bank holidays usually follow Sunday hours (10:30 AM–4:30 PM), but always double-check their website if you’re planning a bank holiday feast. Christmas and Easter are completely different beasts—the store might close early or open later, so if you’re craving a Boxing Day turkey sandwich, have a backup plan.
One year, my husband showed up on Easter Monday at 2 PM, only to find a “Sorry, We’re Closed” sign. He spent the rest of the day crying into a bowl of bland pasta. Don’t be my husband. Check the dates.
