Yes, some supermarkets may be open on Christmas Day. While many stores are closed on Christmas Day, there are usually a few that remain open to provide essential services and supplies to customers. These stores often have limited hours and may have reduced inventory, but they can be a helpful resource if you need something urgently or are unable to purchase items beforehand. It's a good idea to check with your local stores before Christmas Day to find out which ones will be open and what their hours will be.
