> Quick view: the AFFIN Credit Card Buy 1 Free 1 (code ZAFFB1F1) ended on 31 August 2026 and AFFIN has not renewed it. Three ZUS Coffee codes still work in September 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).

The AFFIN Buy 1 Free 1 has ended

AFFIN Bank's "Buy One Free One ZUS Coffee with AFFIN Credit Cards" ran 17 March – 31 August 2026. Because it was a Tuesday-only mechanic and 31 August fell on a Monday, the last usable day was Tuesday 25 August 2026.

Checked again on 5 September 2026: AFFIN's own promotions index still carries the ZUS card, and the detail page still prints the code and the steps — but the stated Promotion Period is unchanged at *"17 March 2026 – 31 August 2026"*. There is no September successor anywhere in AFFIN's 14-item Food & Dining list. The listing is lapsed, not live. Entering ZAFFB1F1 in the ZUS App today will not apply.

This is a common trap with bank promo pages: the page stays published long after the campaign closes, so a live-looking URL is not proof of a live offer. Read the Promotion Period line, not the fact that the page loads.

What still works at ZUS Coffee in September 2026

| Code | Who can use it | What you get | Minimum spend | Limits | Runs until | | --- | --- | --- | --- | --- | --- | | `ZUSB3F1` | Anyone with the ZUS App | Buy 3 Free 1 — the cheapest of four handcrafted drinks drops to RM0 | 4 eligible handcrafted drinks | 1 redemption per person per promo day; Tuesdays only | Ongoing; re-declared from 1 Sep 2026 | | `ZUSBSN5` | BSN Credit Card/-i holders | RM5 off — a RM11.20 bill becomes RM6.20 | RM11.20 total bill | 4 redemptions per cardmember per month; first 775 redemptions a month nationwide | 31 December 2026 | | `ZMBMRM5` | Bank Muamalat Credit Card-i holders | RM5 off handcrafted drinks | RM10 total bill | 1 redemption per cardholder per day; first 250 cups a month nationwide | 31 January 2027 | | ~~`ZAFFB1F1`~~ | AFFIN Credit Card | Buy 1 Free 1, Tuesdays | RM10 | — | Ended 31 Aug 2026 |

All three live 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 stacked with another ZUS voucher, discount or membership privilege.

ZUSday Buy 3 Free 1 — `ZUSB3F1`

The one that needs no bank card. Add four eligible handcrafted drinks to your cart on a Tuesday, enter `ZUSB3F1`, and the lowest-priced one in the cart is discounted to RM0. Pickup and delivery both qualify. One redemption per customer per promo day.

Two things worth knowing: the free cup does not count toward your ZUS Coffee Club cup collection or membership-level upgrade, and the offer excludes 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.

It only pays if you are actually buying four drinks — a group order, or an office run. Solo, it does nothing.

BSN Credit Card RM5 off — `ZUSBSN5`

BSN's own promotion page states the offer plainly: pay with a BSN Credit Card/-i, enter `ZUSBSN5`, and RM5 comes off a total bill of RM11.20 or above — BSN's page gives the worked figure as *"only RM6.20"*. Valid for both pickup and delivery.

The caps are the interesting part. You get 4 redemptions per cardmember per month, and the campaign releases 775 redemptions a month nationwide, first come first served. The exclusion list is unusually short — only 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 (updated 31 July 2026) sets the campaign at 1 August 2026 (12.00AM) to 31 January 2027 (23.59PM). Pay via the ZUS app with a Bank Muamalat Credit Card-i, enter `ZMBMRM5`, and RM5 comes off a minimum total bill of RM10.

The daily allowance is better than BSN's — one redemption per cardholder per day rather than four a month — but the national pool is much tighter at 250 cups per month, first come first served. In practice that pool is the binding constraint, not your personal limit.

Muamalat's excluded-outlet list is the longest of the three: 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

  • Buying one or two drinks, any day of the week: `ZUSBSN5` if you hold a BSN card — it is the only one of the three with a per-member allowance you can realistically use more than once (4 a month) and a pool big enough (775 a month) to still be there mid-month. `ZMBMRM5` is the fallback if you bank with Muamalat.
  • Buying four drinks on a Tuesday: `ZUSB3F1`, every time. A whole cup free beats RM5 off, and it needs no card.
  • **Buying four drinks on a Tuesday *and* holding a BSN or Muamalat card:** you cannot stack them — both banks' terms bar combining with other ongoing ZUS promotions. Take whichever discount is larger; on a four-drink order that is almost always the free cup.
  • Redeem early in the month. All three are capped nationally per month and reset on the 1st. The 250-cup Muamalat pool in particular can be gone well before month-end.

ZUS does not publish drink prices on zuscoffee.com — the RM11.20 and RM6.20 figures above come from BSN's own promotion page, and the RM10 minimum from Bank Muamalat's T&C PDF.

How to redeem, step by step

  1. Download or open the ZUS Coffee mobile app and sign in.
  2. Choose Pickup or Delivery and set your outlet — check it is not on the exclusion list for your code.
  3. 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) do not count.
  4. At checkout, enter the code in the Vouchers field.
  5. For `ZUSBSN5` or `ZMBMRM5`, select credit card as the payment method and pay with the matching BSN or Bank Muamalat card. `ZUSB3F1` has no payment-method requirement.

If you hold an AFFIN Credit Card

The ZUS tie-up is gone, but two AFFIN offers checked live on 5 September 2026 are worth knowing:

  • Jo's Cha — RM6 off with a minimum spend of RM20. Runs now to 14 January 2027, in-store only at any Jo's Cha outlet, not valid for online or delivery orders. It is the nearest drinks substitute in AFFIN's Food & Dining list.
  • Buy 1 Free 1 movie tickets at GSC or TGV. Buy one Standard 2D ticket at GSC or one Adult Deluxe single-seat ticket at TGV online with an AFFIN Credit Card, every Friday and Saturday, and get one free. Promotion period 17 April – 31 October 2026, limited to 100 complimentary tickets per day nationwide, online purchase via the GSC or TGV website or app only.

Verification

Checked on 5 September 2026. The AFFIN status was read from AFFIN Bank's own promotions index at affinalways.com and from the ZUS campaign's own detail page, which still shows the unchanged 17 March – 31 August 2026 period; AFFIN's full 14-entry Food & Dining list was enumerated and contains no renewed ZUS offer. The BSN terms were read from BSN's own promotion page at bsn.com.my. The Bank Muamalat terms were read from Bank Muamalat's promotion page and its own hosted campaign T&C PDF (updated 31 July 2026). The ZUSday Buy 3 Free 1 mechanic, code and exclusion list are as reported for the 1 September 2026 re-run; ZUS Coffee itself publishes no promotions page and no prices on zuscoffee.com, so campaign detail for ZUSday could not be confirmed against a ZUS-owned page and rests on the aggregator record of the same standing campaign, which has run every Tuesday since at least April 2026.
