Transcript for Best Deals of the Year Might Come Before Black Friday
Getting ready to hit the stores this black Friday? More than 140 million Americans expected to shop till they drop this Thanksgiving. But it turns out, the best deals might not be at the end of the week. Here is ABC's Rebecca Jarvis. Reporter: For all the hype, it turns out you don't have to brawl over bargains on black Friday to get the best deals. That is because the biggest sales of the season start tomorrow. And the very best day to gobble up deals is the same day you gobble up Turkey. Black Friday is really like black week. Reporter: How do you know when a deal is really a deal. We enlisted shopping guru mark Ellwood who uses this simple rule of thumb. You shouldn't buy anything that is less than 30% off. Reporter: He says wait. Prices will go lower. And to make sure, turn to social media. One of my favorite ways to learn about the secret discounts is Twitter. Reporter: Tip two, arm yourself with the latest saving apps if you have shopping online. My favorite tool is poach it. It's like a discount ray gun. When you've got sit LG in your shopping basket and you're just about to buy it, click the button and it will scrape the internet for discounts available for that item. Reporter: Tip three. Go for gift cards. Raise and full granny help you buy gift cards for up to 30% off. You can give up as a gift or use them yourself to double up on discounts at your favorite stores. And when in doubt, Ellwood says, just ask. That helps a great deal. Nothing beats a smile. If you say nicely to the sales person, I would rather buy this right now, but it's chiefer if I use the app, will you match it? Show them the app. Reporter: Shopping early and shopping smart.
