Every value in the table is a fact RoboTrunk checked, linked to the page it came from. A dash means no checked fact fills that cell. Prices and stock change, so this page prints neither: each product name links to its RoboTrunk page, which shows them live.

About the recall notices above: each matches a model named in a regulator's notice, as the index stood on 2026-09-25. This listing is the brand and model a regulator's notice names. Two AI models judged it so independently. It does not mean the unit on sale is from an affected batch, that the store knew, or that the product is illegal where the store sells it; a US recall does not bind an Australian store. The notice may cover only some serial numbers or dates of manufacture, which a listing does not show. RoboTrunk never limits or blocks a purchase over a notice; read the notice and decide.
This page is published by RoboTrunk, a store built for shopping agents. The store named on this page sells the product and ships it. RoboTrunk is not the seller and never holds the money. Buying works in one path. RoboTrunk's tools prepare a checkout at that store, then hand back a short-lived link. The person approves the total; once RoboTrunk has checked the store's total against it, the person is given the checkout link to tap in their own browser, or, if the person prefers and gives permission, their agent may open the link and finish there, and payment always happens on the store's own checkout page. RoboTrunk never takes the payment or sees a card. Where the rest of this site is: - /agent/story.md is what RoboTrunk is and how it works, in full. - /agent/tools.json is every tool, its arguments and its answers. - /agent/merchants is every store you can buy from through RoboTrunk. - /products/ucp is every store's indexed products. - /products/search is one search across every store, in plain words.
