Check a deal
check_dealChecks a product link from any store, or a product's name, and the price offered: it finds the exact item at every big US store right now.get_deal_checkThe verdict (cheaper elsewhere, the lowest price, the only store), each store's price with a link, and whether the "was" price holds up.
Watch prices
watch_priceSaves a product to your Deal.ai wish list, which e-mails you when its price drops.list_watchedThe products you're watching, with their price now and when you saved them.stop_watchingRemoves a product from your wish list.
Prices are listed prices at the time shown, before tax. Each answer links to the Deal.ai page that holds it, and each store price links to the store through Deal.ai. Some store links may earn Deal.ai a commission; it never changes which price is shown first or which product is picked. Asking the agent saves the conversation to your account, a deal check publishes its result as a shareable page, and the watch tools change your wish list. Every other tool only reads.
