Version update

Updating to v1.1.3

Already have BUCKS installed? Here's how to get the latest version.

Automatic update

Chrome updates extensions automatically — usually within 24 hours. If you installed from the Chrome Web Store, v1.1.3 will arrive on its own.

Force update now

Open chrome://extensions, enable Developer mode, then click the Update button at the top of the page. All extensions update immediately.

Verify the version

Open the BUCKS popup and check the diagnostics panel — the version shown should be 1.1.3. If it still shows an older version, try the force update again.

Sideloaded an earlier version? Download v1.1.3 ZIP and reload in chrome://extensions.

What's new in v1.1.3

v1.1.3 is a CWS readiness release. Changes: security header hardening (CSP, CORS, CSRF), improved error handling with structured error codes, enhanced observability logging, additional redirect guardrails for sensitive Amazon pages, commission tracking admin tools, and kill switch banner improvements. No changes to permissions, data collection, or cashback calculations.

How it works

What BUCKS actually does.

Affiliate link management

On an eligible, untagged Amazon.com product page BUCKS automatically adds its affiliate tag and shows the estimated cashback. This is the same mechanism used by millions of product review sites — BUCKS just shares the commission with you instead of keeping it.

Estimated cashback

After a purchase, Amazon reports the confirmed commission to us (usually 60–90 days later). We distribute the agreed portion to your BUCKS balance. Amounts are estimates until Amazon confirms. Your price is never affected.

Amazon.com only, nothing else

BUCKS only runs on https://*.amazon.com. It is completely inactive on every other website. No browsing history is captured or stored.
