The 5% figure is the total rate
KAST tops up the rate that would otherwise apply to eligible KAST Business advertising spend. Free-plan transactions move from 3% to 5%. Paid-plan transactions move from 4% to 5% within the first $1 million of spend and from 3% to 5% after that threshold.
The campaign does not add five percentage points on top of the normal cashback rate. It also does not change the permanent cashback values used in the KAST Card profile or score.
Check the merchant category and settlement date
A purchase must qualify as advertising spend under KAST's campaign rules and settle within the promotional period. A merchant's name alone does not guarantee the transaction will use an eligible category code.
KAST can reject refunded, reversed, disputed, fraudulent or otherwise ineligible transactions. The terms currently leave the payout period unfinished, so participants should not assume a specific credit date.
