Real-time credit card deal alerts including bonus changes, limited-time offers, and new card launches.
The deal feed is the running log of what changed recently: welcome bonuses that went up or down, offers that appeared or expired, and elevated shopping-portal rates. It is a monitoring surface for people already following the market, not a starting point for choosing a card.
Timing matters most on bonuses. An elevated offer is usually temporary, so the useful question is whether you were already planning to open that card, not whether the number looks big today.
Anything you act on here is worth confirming on the issuer's own page first. The feed records what we observed and when; the issuer's application page is what governs the offer you actually get.
Issuer pages are re-read on a regular cycle, and a change is only published after separate reads agree, which trades a little speed for not reporting a page variant as a real change.
Only if the card already fit your spending. A larger bonus on a card you would not otherwise carry is not a reason to open it.
On the welcome bonus tracker, which lists every card's current bonus with the date each was last verified.
