If you absolutely must go in person, aim for the 3 p.m. sweet spot. The morning rush has died down, the afternoon nappers are at home, and the reduced shelves are often restocked one last time.

So there you have it: M&S on Boxing Day is a choose-your-own-adventure with slightly confusing opening hours. Whether you go early for the cheese, late for the discounts, or stay home for the online sale, just remember: check first, queue second, and never underestimate the percy-pig-obsessed masses. Now, go forth and exchange that ugly sweater. And if you see Dave, tell him Rudolph says “hello.”
