When planning a Christmas sale, consider the type of promotion you want to offer. You could provide a percentage discount, a buy-one get-one free promotion, or offer a free gift for customers who spend a certain amount. Once you decide on the specific sale, create Christmas-themed social media posts, advertisements, and digital promos you can email to your customers. Add holiday decor to your site or storefront to attract even more customers and show that you’re hosting a sale for Christmas.
