Google rolls out “Universal Cart” in the U.S., aiming to consolidate holiday shopping across stores

Google is expanding a new shopping feature it calls Universal Cart in the United States, rolling it out across Google Search and the Gemini app for the holiday season. In a product announcement on its blog, Google positioned Universal Cart as a way to reduce the back-and-forth of shopping across many websites, by keeping a shopper’s items, savings opportunities, and checkout options in one place.

The company said the cart functions as a persistent hub while customers browse. Rather than relying on browser tabs or screenshots, Google says shoppers can save items from multiple retailers into a single cart and return later without losing their progress, including example products saved from retailers such as Steve Madden, Quince, Ulta Beauty, and more.

A central feature of the product is ongoing monitoring of retailer listings. Google said Universal Cart is built on Google’s Shopping Graph, which it described as 60+ billion continually refreshed product listings. That data foundation, Google said, enables the cart to work in the background and send notifications about price drops and when items come back in stock.

Google also said Universal Cart is designed to help shoppers identify discounts that might otherwise be missed. The cart’s “intelligent reasoning” can surface relevant promo codes and help users choose between payment methods. In particular, Google said the cart is built on Google Wallet, allowing it to understand card perks and help recommend payment options based on what users carry.

When shoppers are ready to buy, Google said Universal Cart supports checkout paths intended to preserve trust and clarity about who sells the goods. The company said users can check out securely through Google Pay in the cart with many of its favorite stores, or they can transfer items directly to the merchant’s site to finish the purchase on the retailer’s platform. Google stated that merchants provide direct confirmations and customer support, and remain the seller of record.

Google also tied Universal Cart to an internal “commerce protocol” it called the Universal Commerce Protocol (UCP). In the company’s description, UCP is part of how the cart supports checkout inside Google experiences while still routing the final purchase through trusted merchant processes.

The rollout includes a broad set of retail partners, which Google named explicitly in its blog post. Those examples included Nike, Sephora, Target, Ulta Beauty, Walmart, Wayfair, and various Shopify merchants. Google did not describe partner-by-partner timelines or whether certain retailers have additional capabilities beyond those routes.

From a product strategy standpoint, Google framed Universal Cart as part of a broader push in commerce that spans both AI-driven “agentic capabilities” and practical tools that help shoppers manage decisions. In this view, the cart is the practical interface, designed to keep shoppers in control and confident about where their items are saved, what savings may apply, and how to complete checkout.

What Google did not spell out in detail is the exact rollout mechanics for every shopper, such as whether the cart’s monitoring coverage varies by retailer, region, or specific product categories. It also did not provide measurable performance data, such as how often notifications lead to purchases or how frequently shoppers use the promo code and payment recommendation features, nor did it describe any limitations around eligibility for price-drop alerts or stock notifications.

For shoppers, the immediate question is how Universal Cart changes day-to-day behavior during holiday shopping: whether it reduces the need to juggle multiple sites and whether the price-drop and promo suggestions meaningfully narrow the search. For Google, the next watch items are likely to include expansion beyond the initial U.S. availability, improvements to the cart’s personalization over time, and further disclosures about Universal Commerce Protocol capabilities as more merchants adopt the checkout flows.
