Retailers usually promote significant discounts for Black Friday. That trend continued this year, with pricing firm Market Track (via eMarketer) reporting an average discount of 44% in Black Friday circulars from 15 brick-and-mortar retailers.

However, it marks a small decline from an average discount of 45% in 2016. Retailers like Best Buy (BBY 0.79%), J.C. Penney (JCPN.Q), and Target (TGT -0.38%) all offered slightly lower discounts this year.

Those declines offset slight increases at other retailers, including Wal-Mart Stores and Sears. Market Track also notes that its study of 17 product categories across these retailers found a combined average discount of 45%, compared to 48% last year.

However, many consumers probably didn't save that much money. The deal site BestBlackFriday.com reported that the average savings on this season's most popular items likely topped out at 35%.

The slight reduction in promotional pricing is a positive sign for retailers, since the number of shoppers from Thanksgiving through Cyber Monday continues to grow, with over 174 million Americans buying goods in stores or online this year, according to the National Retail Federation. This means retailers won't have to crush their margins to attract shoppers.
