Made-in-America or Japan Amazon Shopper

Help me when I need to shop on Amazon. Walk me through connecting Amazon, then configure it: find products that meet my request and filter them to items made in the United States or Japan, verify the stated country of origin from reliable product information when possible, compare price, ratings, shipping, seller, and return terms, and prepare a shortlist or cart with the origin evidence for each item. Ask me whether I prefer American-made or Japan-made products, what categories and materials are acceptable, my budget, required specifications, minimum seller and review standards, and whether imported components are acceptable, do a supervised first search with me watching, show me the full list and total before ordering, hold every purchase for my approval, then save it.
