Amazon announced Alexa for Shopping - rolling out to everyone if you are signed into an Amazon account (no Prime membership or Alexa app needed). Seems like they took a lot of pages out of Google's book including:

• Ask questions in the Amazon search bar or in the dedicated Alexa for Shopping chat window
• AI overviews in search and on product pages
• Product price history for past year
• Dynamic product comparisons
• Personal preferences/shopping history
• Shopping guides for big purchases
• Schedule purchases

But the most interesting part is in two places they say Alexa for Shopping works on other stores too, not just Amazon:

"The combination of deep product expertise and seamless personalization makes Alexa for Shopping the best AI assistant for shopping on Amazon and other stores from across the web."

*"Shop other retailers across the web:* Discover hundreds of millions of products in Amazon's store and from stores across the web through Shop Direct. For eligible products, the Buy for Me agentic AI feature handles the entire purchase on your behalf using your primary address and credit card."
