Watch the seller. Notice the change.
Keep a focused list of storefronts you trust as research signals. When a new ASIN appears, you get a starting point—not a promise that the product is profitable.
The sellers you follow keep adding products. Storefront Sentry watches their Amazon storefronts for new ASINs and sends an alert when something changes—so you can spend your time researching, not refreshing.
