Good sellers move. Your tabs don't.

Storefront stalking works because other sellers can surface product ideas you would not have searched for yourself. But manually opening the same stores again and again is slow—and easy to forget.

From repeat checks to one signal

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.

Focus beats noise

Track sellers that matter to you.

Your sourcing strategy decides the watchlist. Sentry helps you follow it consistently.

Discovery ≠ decision

See the ASIN. Then do your homework.

Open the listing and check sales history, competition, sourcing cost, fees, and eligibility before you buy.

From a seller ID to a useful heads-up.

Four simple steps. Click through the sample flow to see what you're getting.

What is a storefront stalker?

It's a tool that watches the Amazon seller storefronts you choose. When a seller adds an ASIN, you can review it as a possible product idea.

Does an alert mean the product is profitable?

No. A new ASIN is a research lead, not a buying recommendation. Check demand, sourcing cost, fees, competition, and selling eligibility before purchasing inventory.

Do I choose which sellers to track?

Yes. You build a watchlist around the sellers relevant to your niche and sourcing approach.

Where do alerts go?

Storefront Sentry supports webhook alerts, so you can send new-ASIN signals to a destination in your workflow. Recent activity is also available in the dashboard.

Is this the same as a full product research tool?

No. Sentry helps you notice new additions. Keep using your preferred tools to assess sales history, fees, restrictions, and whether you can source the item at a workable cost.
