Catch lower prices while browsing
Open any supported product page and the extension checks GunAmmo.Deals for live comparison pricing without forcing you to start your research over.
Price check anywhere
Turn any retailer product page into a live GunAmmo.Deals comparison screen.
The GunAmmoDeals browser extension reads public UPC and price signals on supported pages, shows the best live matches we have on file, and lets you jump straight to the compare page before you overpay.
12-13
Digit-only manual UPC lookup when a store page does not expose a clean identifier.
Top 3
Fast price and stock snapshot from the latest GunAmmo.Deals crawl.
1 click
Jump from a store page to View All deals for that UPC without starting over.
How you save money
You catch the price gap before you click Buy.
The example above mirrors the exact moment the extension matters: a retailer page looks fine until GunAmmo.Deals shows the same UPC available elsewhere for less. That is the difference between browsing blind and browsing with live comparison data.
Use the page UPC or paste one yourself
If a store page hides or mangles the UPC, paste a 12 or 13 digit UPC directly into the popup and search manually.
See availability before you click out
Top matches include stock status and direct compare links so you can decide whether it is worth leaving the page you are on.
How it works
Fast enough for impulse checks, detailed enough for real research.
You do not have to leave the store page, copy titles into search, or guess whether the listed sale price is actually competitive.
1
Install the extension
Add it from the Chrome Web Store or Edge Add-ons and pin it so it is one click away during product research.
2
Open a product page on another retailer
The scanner reads public identifiers such as UPC or GTIN and checks GunAmmo.Deals for price and stock matches.
3
Compare the best market price
If the page price is higher, jump straight to the compare page or View All to keep digging for a better deal.
Manual UPC lookup
If detection fails, paste the UPC and keep moving.
Some stores bury identifiers in awkward layouts or partial markup. The popup now accepts a 12 or 13 digit UPC, strips everything except integers, and still gives you the compare screen and View All fallback even when there is no direct match yet.
Paste UPC if it is not detected

Privacy by design
The extension reads public product identifiers and visible price text from the active page after user action. It does not handle payments, credentials, or checkout.
Built for Chrome and Edge

Built to support research, not transactions
You stay in control of where you buy. The extension only helps surface better information and faster price comparisons.
Install now
Add the extension before your next product search starts costing you money.
Compare what the current page is asking against the market price GunAmmo.Deals already tracks, then decide whether the listing is actually worth your click.
Does the extension handle checkout or payments?
No. It is a research tool only. It does not provide checkout, cart, or payment handling.
What information does the extension read?
It reads public product identifiers and visible price text from the active page after user action. It does not collect passwords, form contents, or payment information.
What if the page UPC is missing?
Use the manual UPC field in the popup. The input only accepts digits and supports 12 or 13 digit UPC values.
