A card’s sign-up bonus is usually the single biggest reason to get it — and the offer moves a lot. The same card might give 60,000 points one month and 100,000 the next. Apply at a low point and you can leave tens of thousands of points on the table that you can never get back. The hard part is knowing where today’s offer sits in that history. That’s the work we do for you.
Every public sign-up offer for each card, sourced from trackers like Upgraded Points and Doctor of Credit, going back years.
The biggest welcome bonus the card has ever offered — the benchmark today's deal has to beat.
Checked daily. A card only appears on this list while its current bonus ties its own record.
