Privacy by Design

You're always
in control.

Tired of intrusive extensions that slow your machine, hijack cookies and aggressively spam checkouts? The BudgetFitter Extension works differently — it only activates when you want it to.

One Click to Copy

Browse the list, copy your preferred code with one click, and apply it yourself at checkout. You decide when to use it.
Smart Auto-Apply NEW

On supported checkouts, click the "Auto-Apply" button — the extension rapidly tests verified codes and locks in the best value. We only run it on your command.

Transparency & Privacy

Transparency First. We do not harvest general browsing history. The extension only activates on domains where we have verified deals.

How we stay free. We may earn a commission from offers you find — that's what keeps the utility free. Always verify the offer before completing payment.
