It also tracks price cuts, shows relevant promo codes and can [finish purchases through Google Pay](https://www.trendhunter.com/trends/agentic-checkout-paths) or send items to a merchant's site. Built on Google's [Shopping Graph](https://www.trendhunter.com/trends/morrisons-3), with more than 60 billion refreshed product listings, the cart can flag when an item drops in price or comes back in stock. Its link to Google Wallet also uses stored card perks to suggest which payment method fits a purchase. Its availability across Search and Gemini turns shopping on Google into a tighter hybrid of [discovery, savings and checkout](https://www.trendhunter.com/trends/aipowered-shopping-experience). A cross-store cart that stays synced across those surfaces shifts expectations toward fewer tabs and screenshots, while still leaving the merchant as the seller of record.
