Frequently Asked Questions
Can I combine multiple promotions?
Promotions apply individually to each submission type. Bulk bonuses stack with the current grading rate when you submit multiple cards at once — check each active promotion's details to see how they work together.
Who qualifies for these promotions?
All registered SlabSharks customers qualify automatically. Some promotions may have additional requirements, such as a minimum card count or submission type, listed on each offer.
How long do promotional rates last?
Each promotion has its own active window shown on the offer card. Your rate locks in when your submission is received, so it won't change mid-shipment.
Do promotions apply to both raw and graded cards?
Most promotions apply to both raw and graded submissions, but a few are limited to one type. Check the offer details before submitting to confirm eligibility.
How do I redeem an active promotion?
No code needed — eligible promotions apply automatically when your submission matches the offer's requirements, and you'll see the applied rate in your order summary.
