Notice this deal is back from Citibank. Unfortunately the fee is not as good before - now $300 instead $150, but still not bad if considering other perks with Premier card.
To be eligible to receive $600 cashback, you must spend a minimum of $2,000 on eligible purchases using your new card through Apple Pay or another eligible digital wallet within 3 months from approval. Excludes Citi PayAll payments, Cash Advances, Balance Transfers, Special Promotions, interest and fees. Any refunds and Chargebacks on purchases will also be excluded and will not form part of the spend criteria. "Another eligible digital wallet" means Samsung Pay or Google Pay. Cashback will be credited to your Account within 4 months of meeting the spend criteria.
$300 profit and other perks (Priority Pass lounges, Complimentary Travel Insurance, etc)
Not really great deal but may be for someone ran out of cards for churning.
Citibank cc applications can be good (IMO) or a pain (YMMV) to deal with.
"Not really great deal but may be for someone ran out of cards for churning." You summed up my situation perfectly, OP. We are doing more local holidays in the future so I am more interested in cash deals like this one compared to frequent flyer points.
Edit: Cashback will be credited to your Account within 4 months of meeting the spend criteria. That is outrageous!
