U.S. consumers spent nearly $11 billion online on Black Friday, shattering a record this holiday season, with Mastercard saying retail sales jumped 3.4 percent from last year. An NBC News price analysis also revealed that the cost of goods like tech gadgets to toys were at the lowest prices since at least July.

Online brands saw big growth on Black Friday, but it came at the expense of in-store shopping. The extended promotional period also hurt Black Friday.

Black Friday spending in U.S. retail stores was muted this year in contrast to a more robust rise online, as bargain-hungry Americans skipped stores in favor of their phones and laptops, according to data from Mastercard and other data providers.
