U.S. retail sales rose 1.2% month over month in August, beating expectations, according to the U.S. Census Bureau's monthly sales report. The gain was not just a gas-pump effect. Electronics and appliances climbed 1.6%, furniture and home furnishings rose 0.9%, and clothing and clothing accessories gained 0.7%. Nonstore retail jumped 2.6%.

The strong August report landed amid a week of major moves from Amazon, plus early holiday promotions from Walmart, Target and Best Buy.

Amazon raises its wage floor

Amazon will raise the minimum wage for its full-time core operations employees to $20 per hour, bringing average pay to nearly $24 per hour. The $1 increase represents a $1.5 billion investment from the company, which is also expanding benefits. New perks include a lifetime membership in the First Tech Federal Credit Union, 10% off everyday essentials on Amazon.com and Whole Foods Market online, and 20% off in store at Whole Foods Market.

The wage announcement landed on the same day Business Insider reported, based on a review of internal documents, that Amazon plans to build 1,000 same-day delivery facilities by 2031. The report found the hubs would sit within 10 miles of 80% of Amazon Prime customers.

The buildout positions Amazon to challenge Walmart on delivery speed. It also raises the stakes for retailers competing on fulfillment convenience heading into the holiday quarter.

Holiday promotions start earlier than ever

The holiday sales season is ramping up earlier than ever this year. Amazon and Target both announced major deal days in October. Best Buy launched its holiday gifting center earlier than in previous years, joining Walmart and other major players in extending the season.

Target confirmed the return of Target Circle Deal Days in a press release promising major savings on fall and holiday finds. Best Buy's earlier holiday preview signals retailers are competing for shopper dollars weeks before Thanksgiving.

Deloitte sees 4% to 4.8% holiday growth

Holiday forecasts are starting to roll in. Deloitte predicts holiday sales gains between 4% and 4.8% from last year. The research firm expects e-commerce to outpace the overall market, rising between 7.5% and 8.4%.

For marketers, the combination of stronger-than-expected August sales, an earlier promotional calendar and robust e-commerce forecasts points to a compressed, highly competitive fourth quarter. Brands that lock in media plans and inventory early stand the best chance of capturing the seasonal spend.
