Yes, most T.K. Maxx stores are open on Boxing Day. But—and I’m whispering this so Dave doesn’t hear—they usually open later than a normal day. Think 9 a.m. or 10 a.m., not the pre-dawn madness of Primark. You can bet the store will be busy, but it’s not a black-friday-esque war zone. You’ll find a parking spot, I promise.
Check your local store’s times online, because locations vary. I once drove twenty miles to a T.K. Maxx that was “open” and found a handwritten sign saying “Staff recovering from Christmas Pudding.” True story. Don’t be like me. Use their store locator, or you’ll end up eating a cold mince pie in the car park.
