Not Following Retailers on Social Media
Sara Skirboll, shopping and trends expert for RetailMeNot, recommends following retailers on social media. Also, sign up for some retailers' email newsletters.
Ignoring Facebook and Twitter updates means you could miss out on coupon codes or links to special offers. Newsletters for first-time shoppers might include a one-time discount.
What to do: "If you are not inclined to go out of your way to research deals before you shop, follow your favorite retailers on social media so you can see what sales they are having before you go to the store," she said. "Additionally, sometimes they will post special sales and offers exclusively for their followers. After the holiday season, you can unfollow the accounts and unsubscribe from their newsletters to cut back on spam to your feed and inbox."
