US Thanksgiving and Black Friday online sales hit record levels while foot traffic in retail stores was down slightly at most locations.

Preliminary reports from Adobe Analytics say Thanksgiving Day and Black Friday online sales totaled $7.09 billion, up 17.9% from the year before. Black Friday sales alone totaled $5.03 billion.

Adobe predicts Cyber Monday sales will total $6.6 billion, the highest ever for a single day of online sales in the US.

Mobile sales jumped 11%

Market research firm Criteo said 40% of sales were made on mobile phones compared with 29% last year.

While in-store retail sales were not yet available, some analysts said foot traffic and parking lots appeared somewhat less crowded than previous years. ShopperTrak said store traffic fell 1% on Black Friday and 1.6% for Thanksgiving and Black Friday combined.
