What's more, the financial education site said several retailers this month have already offered the same or lower prices as their Black Friday deals.
"This is the fourth year we've conducted this analysis, and we're still seeing repetitive deals every year," said NerdWallet shopping manager Katrina Chan. "Just because a retailer promotes a certain product as a 'deal,' consumers shouldn't take that at face value. Shoppers still have to do their homework early."
NerdWallet listed Belk as the biggest offender for repeat deals, saying it duplicated at least 80 in this year's Black Friday ad. Macy's came in second, with more than 60 repeated deals. Only Dell did not advertise any of the same deals, according to NerdWallet.
