Case study

When a sign-up bonus outranks your dining card

I have an open $4,000 minimum-spend requirement on a new card — should I still use my 4× dining card at restaurants?

Scenario

Wallet: Amex Gold (4× dining), Chase Sapphire Preferred (3× dining, $4,000 / 3-month spend requirement still open, $750 bonus).

The Sapphire bonus is worth roughly 60,000 points ≈ $750 once the requirement is met.

  2. 2. Live offers

    None active — skip.

  3. 3. MSR gating

    Sapphire has an open, unmet $4,000 requirement. The $750 bonus dwarfs the ~$0.22 category gap, so spend is steered to Sapphire to make progress toward the bonus.

Result

Swipe Sapphire Preferred. Even though Amex Gold earns slightly more on this one charge, completing the sign-up bonus is worth ~$750 — the router prioritizes the requirement until it is met.
