LEGO sets, Hot Wheels cars, board games and Paw Patrol figures sell at genuinely different prices from one supermarket to the next, and the gap widens around birthdays and Christmas. We compare LEGO, Hot Wheels, Uno, Monopoly, Nerf and Paw Patrol ranges at Tesco, Sainsbury's, ASDA, Aldi, Morrisons, Co-op, Waitrose, Iceland, B&M, Boots, Superdrug, Savers and Ocado (including M&S) every day. Check here before a birthday shop instead of paying whatever the first aisle you walk down happens to charge.
