Televisions, headphones and electronics, as always, are expected to be a big draw at big-box stores like Walmart and Target. Department stores that offer big discounts, like Macy’s, will remain a top destination during the weekend, too. Macy’s website is blanketed with its Black Friday promotions, with ads for everything from coats to Apple watches to blenders. “Black Friday Starts Now!” declares a big banner at the top.

But discount and dollar stores, which generally haven’t been big draws on Black Friday, are also expecting strong sales. Over all, dollar stores will experience one of the biggest rises in turnout this year over last year, according to a survey of more than 2,000 adults by the data company Nielsen.

Phillip Dengler, the co-owner of the website BestBlackFriday.com, which monitors the annual sales, said he had seen more of a push from low-budget stores this year. He pointed to the discount chain Dollar General as an example: The company has extended its hours, and Mr. Dengler said the chain had made more of an effort to get its Black Friday circulars online and in front of customers.

“When you think about Black Friday, you don’t think about Dollar General, you think about Walmart and Target and Amazon,” Mr. Dengler said. “They’re trying a little bit more.”

Discounters like dollar stores and so-called off-price stores like T. J. Maxx and Ross also are different in another way from rival retailers: They have little to no e-commerce presence. That has made them somewhat immune to certain industry pressures, and could give them greater incentive to entice people into stores.

“I think e-commerce has allowed for Black Friday to start whenever Amazon wants it to start,” said Simeon Siegel, an analyst with Nomura. For the last few years, Amazon has offered Prime Day, its own annual one-day shopping bonanza. “That doesn’t exist for T. J. and Ross.”

Another trend working in favor of discount and dollar stores is the rising popularity of food and kitchen items, like mixers and cookware, as holiday gifts. That’s in part because of new fads like “Friendsgiving” and “Friendsmas,” when, you guessed it, friends rather than family get together for a holiday meal.
