> Quick view: the AFFIN Credit Card Buy 1 Free 1 at ZUS Coffee is back. Code ZAFFB1F1 works again every Tuesday from 1 September to 8 December 2026, with a RM10 minimum spend, a RM10 cap on the free cup and 400 vouchers a month nationwide. Three other ZUS Coffee codes also work in October 2026: ZUSB3F1 (Buy 3 Free 1 every Tuesday, no bank card needed), ZUSBSN5 (RM5 off with a BSN Credit Card, to 31 Dec 2026) and ZMBMRM5 (RM5 off with a Bank Muamalat Credit Card-i, to 31 Jan 2027).
AFFIN's ZUS Buy 1 Free 1 has been renewed to 8 December 2026
The first run of "Buy One Free One ZUS Coffee with AFFIN Credit Cards" ended on 31 August 2026. In early September AFFIN's site showed only that lapsed listing. By 12 October 2026 AFFIN had published a new listing for the same offer, with the same code and a new period of 1 September – 8 December 2026. It sits at the top of AFFIN's Food & Dining list, and AFFIN's own T&C PDF sets out the terms:
- Code: ZAFFB1F1, entered in the Vouchers field of the ZUS Coffee app.
- Day: every Tuesday. The last date, 8 December 2026, is itself a Tuesday, so nine Tuesdays are left from 13 October.
- Card: an AFFIN BANK Credit Card or AFFIN ISLAMIC Credit Card-i. Supplementary cards count.
- Minimum spend: RM10 in one transaction, not counting delivery charges. Pickup and delivery both qualify.
- The free cup: it must cost the same as the first drink or less, and the discount is capped at RM10.
- Caps: AFFIN's page says the first 100 redemptions every Tuesday nationwide, and its PDF says 400 a month. Each cardmember gets one redemption per Tuesday.
- Excluded: discounted-price items, ZUS Bottled Necessity, bottled drinks, cakes, pastries, hot meals, healthy snacks, merchandise and paid modifiers (extra shot, syrup, drizzle, soy, almond or oat milk).
Worked example: two drinks that each cost more than RM10 meet the minimum, and the cheaper one comes off. If the second cup costs RM14, the saving is still RM10 because of the cap. Ordering one premium drink and one cheap drink saves less than ordering two drinks at similar prices.
With only 100 vouchers per Tuesday for the whole country, the pool can run out early. Order in the morning, not at 4pm.
Every ZUS Coffee code that works in October 2026
- ZAFFB1F1, AFFIN Credit Card/-i: Buy 1 Free 1 handcrafted drinks, with the free cup capped at RM10. RM10 minimum spend. One per cardmember per Tuesday, first 100 a Tuesday (400 a month) nationwide. Tuesdays only, to 8 December 2026.
- ZUSB3F1, anyone with the ZUS App: Buy 3 Free 1, so the cheapest of four handcrafted drinks drops to RM0. Needs four eligible drinks. One per person per Tuesday. Tuesdays only, ongoing (re-posted every Tuesday, most recently 6 October 2026).
- ZUSBSN5, BSN Credit Card/-i: RM5 off a RM11.20 bill, so you pay RM6.20. Four per cardmember a month, first 775 a month nationwide. Any day, to 31 December 2026.
- ZMBMRM5, Bank Muamalat Credit Card-i: RM5 off handcrafted drinks on a RM10 bill. One per cardholder per day, first 250 a month nationwide. Any day, to 31 January 2027.
All four codes are entered in the Vouchers field at checkout in the ZUS Coffee mobile app. None of them work at the counter, and none can be combined with another ZUS voucher, discount or membership privilege.
ZUSday Buy 3 Free 1: ZUSB3F1
This is the only code that needs no bank card. On a Tuesday, add four eligible handcrafted drinks to your cart and enter ZUSB3F1. The cheapest drink in the cart drops to RM0. Pickup and delivery both qualify, it is not available on third-party delivery apps, and each customer gets one redemption per Tuesday.
The 6 October 2026 terms exclude Frappés as well as discounted-price items, ZUS Bottled Necessity, bottled drinks, cakes, pastries, hot meals, healthy snacks and merchandise. The free cup does not count towards your ZUS Coffee Club cup collection or a membership-level upgrade. The excluded outlets are ZUS SkyPark Terminal, KidZania Kuala Lumpur, Genting 1 (First World), Gateway@KLIA2 (Departure and Arrival halls), Sky Avenue, Langkawi International Airport Food Garden and all ZUS Signature outlets.
The code is only worth using when you buy four drinks, for a group order or an office run. For a solo order it does nothing.
BSN Credit Card RM5 off: ZUSBSN5
According to BSN's own promotion page, you pay with a BSN Credit Card/-i, enter ZUSBSN5, and RM5 comes off a total bill of RM11.20 or more. BSN gives the worked figure as *"only RM6.20"*. The code works for both pickup and delivery.
Each cardmember gets 4 redemptions a month, and the campaign has 775 redemptions a month nationwide, first come, first served. The exclusion list is short: four ZUS Signature outlets (Taman Paramount PJ, Sunway Pyramid Oasis Entrance, Menara Keck Seng Jalan Bukit Bintang and Fahrenheit88).
Runs to 31 December 2026.
Bank Muamalat Credit Card-i RM5 off: ZMBMRM5
Bank Muamalat's campaign T&C PDF sets the period as 1 August 2026 to 31 January 2027. Pay through the ZUS app with a Bank Muamalat Credit Card-i and enter ZMBMRM5. RM5 comes off a minimum total bill of RM10.
You can redeem it once per cardholder per day, but the national pool is only 250 cups a month, first come, first served. In practice the pool runs out before your personal limit does.
Muamalat excludes the most outlets of the four: Suria KLCC, Imago Shopping Mall, Pavilion Damansara Heights, Lot 91 KLCC, The Exchange TRX, SkyPark Terminal, Domestic Departure Gate A Terminal 1 KLIA, Gateway@KLIA2 (Departure Hall Level 3 and Arrival Hall Level 2), KidZania Kuala Lumpur, Genting 1 (First World), Sky Avenue, Selera Putra, Souq Putrajaya, Genting Xintiandi Sales Gallery, Langkawi International Airport Food Garden, AK Antara Signature Mall, Senai International Airport, Coffee Meets Pastry by ZUS at 1 Utama, and all ZUS Signature outlets.
Which one should you use
- Two drinks on a Tuesday with an AFFIN card: ZAFFB1F1. A whole cup free (up to RM10) beats RM5 off. Order early, because the 100-a-Tuesday pool is small.
- Four drinks on a Tuesday: compare first. ZUSB3F1 takes the cheapest of four cups off with no card. ZAFFB1F1 takes the cheaper of the first two off, up to RM10. If the cups cost about the same, the savings are about the same. ZUSB3F1 is the safer choice because it has no national cap.
- One or two drinks on any other day: ZUSBSN5 if you have a BSN card. You can use it 4 times a month, and the 775-a-month pool is unlikely to run out by mid-month. ZMBMRM5 is the fallback if you bank with Muamalat.
- Stacking: you can't. ZUS takes one voucher per order, and every bank's terms forbid combining codes.
- Redeem early in the month. The BSN, Muamalat and AFFIN codes all have monthly national caps that reset on the 1st.
ZUS does not publish drink prices on zuscoffee.com. The RM11.20 and RM6.20 figures come from BSN's promotion page, the RM10 minimums and the RM10 cap from the Bank Muamalat and AFFIN T&C PDFs.
How to redeem, step by step
- Download or open the ZUS Coffee mobile app and sign in.
- Choose Pickup or Delivery and pick your outlet. Check that it isn't on the exclusion list for your code.
- Add your handcrafted drinks. The codes cover handcrafted drinks only. Bottled drinks, cakes, pastries, hot meals, healthy snacks, merchandise and paid modifiers (extra shot, oat milk, extra syrup) don't count.
- At checkout, enter the code in the Vouchers field.
- For ZAFFB1F1, ZUSBSN5 or ZMBMRM5, choose credit card as the payment method and pay with the matching AFFIN, BSN or Bank Muamalat card. ZUSB3F1 works with any payment method.
Other offers for AFFIN cardholders
Two other AFFIN offers are on its promotions index as of 12 October 2026:
- Jo's Cha: RM6 off a minimum spend of RM20, until 14 January 2027. It is in-store only at any Jo's Cha outlet and not valid for online or delivery orders.
- Buy 1 Free 1 movie tickets at GSC or TGV every Friday and Saturday: buy one Standard 2D ticket at GSC or one Adult Deluxe single-seat ticket at TGV online with an AFFIN Credit Card and get a second one free. The detail page gives the period as 17 April – 31 October 2026, limited to 100 free tickets a day nationwide.
Verification
Checked on 12 October 2026. AFFIN's renewed offer was read from its promotions index at affinalways.com (Food & Dining, "Valid till 8 December 2026"), from the detail page and from AFFIN's own T&C PDF ("Sept 2026"), which gives the 1 Sept – 8 December 2026 period, the RM10 cap and the 400-a-month limit. BSN's terms were read from BSN's own ZUS Coffee page, which still says "Valid until 31 December 2026". Bank Muamalat's terms were read from its promotion page, which still gives 1 August 2026 – 31 January 2027, and from its campaign T&C PDF. ZUS Coffee publishes no promotions page and no prices on zuscoffee.com, so the ZUSday Buy 3 Free 1 terms, including the Frappé exclusion, come from an aggregator's record of the 6 October 2026 ZUSday, not from a ZUS-owned page.
