GOOGLE'S NEW UNIVERSAL CART WANTS TO FOLLOW YOUR ENTIRE SHOPPING JOURNEY ACROSS THE INTERNET

Summary from the TLDR Marketing newsletter

Google's new Universal Cart lets users save products from across Search, Gemini, YouTube, and Gmail into a single hub that tracks price drops, flags compatibility issues, and alerts on restocks. The more significant announcement may be Agent Payments Protocol (AP2), which allows AI agents to autonomously complete purchases within user-defined spending limits and brand preferences.
