In case you missed it, last month we wrote about DBS offering their highest-ever cashback promotion with S$300 available for new-to-bank credit card customers who picked up one of six cards, including some popular miles-earning options like the DBS Altitude and WWMC options.

If you’re interested and haven’t taken advantage yet, it’s probably time to do so. The offer ends for applications made this Sunday (10th January 2021). Your card must be approved by 17th January 2021, so it’s better to apply sooner rather than later in case of any holdups.
With no minimum spend required, just one single transaction in the first 30 days, this is the most generous offer we’ve seen from the bank, even beating any of its miles sign-up bonuses for the Altitude cards.
Eligibility
To be eligible, you’ll need to be new to DBS/POSB credit cards, which means currently not holding any principal DBS/POSB credit card and/or having not cancelled any DBS/POSB credit card(s) within the last 12 months.
If you are a supplementary DBS/POSB cardholder but not a primary cardholder on any such account, you’ll also be eligible as a new customer.
The offer
You’ll earn S$300 cashback when you apply online for a DBS/POSB credit card using promo code ‘FLASH300’– with no minimum spend required, just a single qualifying transaction.

Applicable cards are:
![]() APPLY |
![]() APPLY |
![]() APPLY |
![]() APPLY |
![]() APPLY |
![]() APPLY |
Here’s how it works:
- Apply online for one of the credit cards listed above with promo code ‘FLASH300’ between 21st December 2020 and 10th January 2021. Your card account must be approved by 17th January 2021.
- Activate the card within 30 days of your approval date.
- Charge one qualifying transaction to the new card within 30 days of your approval date.
The qualifying transaction must be made by the primary cardholder, not a supplementary cardholder. It can be online or in-person and can be charged in SGD or foreign currency.
The S$300 cashback will then be credited to your card account within 120 days (4 months) of the date of card approval, so for example if your card is approved on 12th January 2021 and you complete the steps correctly, the cashback will be credited by 12th May 2021.
Your card account must remain open and in good standing when the cashback is credited.
Excluded transactions
You only have to make one transaction to qualify for this offer, so make sure it’s eligible especially if that’s the only spend you intend to make during the first 30 days.
Here’s a list of excluded spend categories:

DBS Altitude cards
One of the most popular general spend cards among our readers in the DBS lineup is the bank’s Altitude cards.
There’s still a 10,000 miles sign-up bonus running for these until 31st January 2021, with a cashback alternative of S$150 (Visa) or S$200 (Amex) for a spend of S$800 in the first 30 days.
This S$300 cashback deal is a much better way to qualify for a higher cashback element, which is hiked by S$150 for the Visa card and S$100 for the Amex. Here’s how it looks alongside the bonus miles options:

Bonus Miles |
Cashback |

Promo Code: DBSALT |
Promo Code: ALTAF |
Promo Code: FLASH300 |
↓ | ↓ | ↓ |
Spend: S$6k in 90 days |
Spend: Once in 30 days |

Fee waiver | Annual Fee: S$192.60 |

↓ | ↓ | ↓ |
Bonus Miles: 10,000 Cashback: S$0 |
Bonus Miles: 20,000 Cashback: S$0 |
Bonus Miles: 0 Cashback: S$300 |
S$300 cashback is definitely a better deal than 10,000 bonus miles (which we value at around S$190), and with no minimum spend requirement this could be the perfect time to take the plunge with one of these cards if you don’t currently hold a DBS/POSB credit card and haven’t done for the last 12 months.

DBS WWMC
The other great DBS credit card to have in your wallet (or actually, on your desk at home) for miles earners is the Woman’s World Mastercard (WWMC), which earns 4 miles per dollar for the first S$2,000 in monthly online transactions.
The best part? Men can apply too!

Summary
We don’t usually write much about cashback offers but this one is very generous for those of you who don’t yet have a DBS credit card.
S$300 cashback is much better than a 10,000 miles sign-up bonus in our book, and with no minimum spend, just one single transaction in the first 30 days, it’s a no-brainer to go for this option even for cards offering an alternative miles sign-up bonus.

Remember you must use the promo code FLASH300 when applying to be eligible for this cashback offer, by Sunday 10th January 2021.
If you’re already a DBS credit card customer, check whether any of your supplementary cardholders are eligible. If they don’t have a primary DBS/POSB credit card of their own, and haven’t for the last 12 months, they should really take advantage now.
