Best Buy grew both total revenue and online sales in its fiscal Q3 2026, with CEO Corie Barry calling comparable sales growth “better than expected.”
In its fiscal Q3 2026 — which ended Nov. 1, 2025 — Best Buy revenue reached $9.67 billion. That’s 2.4% growth compared to about $9.45 billion in the prior year’s third quarter. Its U.S. sales accounted for nearly $8.88 billion of that, or about 91.8%.
Global comparable sales increased 2.7% year over year. In the U.S., that growth was 2.4%. Meanwhile, Best Buy international sales grew 6.3% year over year.
Best Buy is No. 8 in the Top 2000. The Top 2000 database is Digital Commerce 360’s ranking of the largest North American online retailers. Best Buy falls under the Consumer Electronics category. Digital Commerce 360 projects Best Buy ecommerce sales in 2025 to grow 2.7% to $13.47 billion.
What drove Best Buy sales in Q3
Best Buy said computing, gaming and mobile phone merchandise drove the largest increases in comparable sales. Declines in sales of home theater equipment and appliances offset growth in those leading categories, the retailer shared.
“We also drove our fastest shipping fulfillment speed ever, coupled with our highest on-time rate for a third quarter,” Barry told investors on the retailer’s earnings call.
Using a data-driven sourcing solution to choose the most efficient location to fulfill more than 70% of online orders, Best Buy has seen faster delivery times, better on-time delivery and lower costs, according to Barry. She also noted that despite advancements in shipping speed, 46% of orders consumers place online are for in-store pickup.
She said September had the lowest growth rate of the quarter, saying it was “relatively quiet outside of the Labor Day sales event.”
Additionally, Barry noted that Best Buy has begun selling across all its stores Meta’s artificial intelligence (AI)-powered glasses. In more than 50 locations, the retailer is also holding immersive showcases featuring Metta experts. It also introduces expanded assortments featuring products from SharkNinja and Breville.
Chief financial and strategy officer Matthew Bilunas said Best Buy’s average sales price of products was practically flat compared to the prior year. An increase in units sold was the primary driver of Best Buy sales growth in Q3, according to Bilunas.
Best Buy has more than 100 million members across its three membership tiers (which include both free and paid levels), according to Barry.
Best Buy online sales in Q3
In Q3, Best Buy online sales revenue in the U.S. reached $2.82 billion, growing 3.5% year over year.
As a portion of total U.S. revenue, Best Buy ecommerce represented 31.8% of sales. That’s a slightly higher online sales penetration than Best Buy recorded in its prior Q3, 31.4%.
That’s the fourth straight quarter that online sales increased. Barry attributed that to higher traffic and increased customer adoption of the retailer’s mobile app. Consumers are increasingly using Best Buy’s app each quarter, according to Barry.
That helps the retailer “recognize more customers as they shop with us and gives us the opportunity to provide better personalization and product recommendations,” she said.
“We improved the online TV shopping experience by both lowering the price for our delivery and installation services and improving the digital flow to make it even easier for customers to add the services to their online TV purchase,” Barry told investors.
Best Buy also launched its online marketplace in its fiscal Q2. About three months into the launch, Barry said the retailer has more than 1,000 sellers and 11 times more SKUs than it did prior to launch. So far, Best Buy has seen high unit sales of accessories and small appliances. Its five-star customer reviews on its third-party marketplace are similar to what it sees in its first-party business, according to Barry.
“Customer return rates for marketplace items have been running lower than our first-party return rates,” Barry said. “And for customers who do have a return, they are taking advantage of the convenient return to store option for more than 80% of product returns.”
Best Buy ad sales in Q3
Barry said the retailer’s third-party online marketplace “is already providing opportunities for Best Buy ads through new advertisers.”
In Q3, Best Buy launched a self-serve platform called My Ads for its marketplace sellers.
Best Buy has “enabled on-site programmatic buying, augmented our reporting capabilities and expanded our on-site ad supply,” she said. “We are successfully expanding into new opportunity areas like agencies and demand-side platforms or DSPs. We are also gaining traction in non-endemic categories, with several partners testing the platform in differentiated ways.”
She also said Best Buy’s retail media network “is already highly profitable.”
How Best Buy is using AI
Best Buy is using AI to “streamline” customer-support interactions, Barry said. She said it has provided “new experiences that empower customers with more self-serve content and options.”
That led to a 17% decline in the number of customer contacts in Q3, she said, while improving customer experience scores.
Best Buy is “increasingly using AI for product search, product recommendations and enriching product content as well as expanding into conversational AI and agentic commerce,” Barry said.
Some agentic commerce offerings feature a capability called “instant checkout.” When it comes to such capabilities, Barry said, retailers must consider how they “want those experiences to translate for the customer. And that’s just when we’re talking about the actual transaction point.”
More broadly, she said, Best Buy is focused on its brand image and how its knowledge of its customers can help. It wants its information to be helpful to consumers “as they’re using a variety … of agentic tools.”
“We’re obviously working quickly to make sure that we are relevant and showing up in the right places,” Barry said. “But most important for us is protecting the customer experience, so that that stays consistent with how we would want them to experience our own digital assets.”
