Challenger has timed a short online sale to the haze, with a campaign banner full of air purifiers and masks and a pitch to shop from home instead.

What the codes are really worth
Both codes come to 4% at their thresholds: $6 is 4% of $150 and $12 is 4% of $300. Spend more and the share shrinks, so a $500 basket with STAY12 saves only 2.4%. Treat the codes as a top-up on top of the markdowns, not as the reason to buy.
The free delivery matters more for small orders. Challenger normally ships free only above $60, so a $45 power bank or a $53 mouse now arrives with no delivery charge.
Markdowns worth a look
These were listed in the Stay-In Specials collection on Saturday morning, 24 October. "Was" is Challenger's own crossed-out price.
| Item | Was | Now | With a code |
|---|---|---|---|
| Samsung 27" ViewFinity S8 UHD monitor | $598 | $358 | $346 with STAY12 |
| HP OfficeJet Pro 9120e all-in-one printer | $349 | $209 | $203 with STAY6 |
| Sony WH-CH720N noise-cancelling headphones | $249 | $149 | add $1+ to reach STAY6 |
| JBL Endurance Race 2 sports earbuds | $179 | $89 | free delivery |
| Nintendo Sound Clock: Alarmo | $159 | $64.30 | free delivery |
| Logitech MX Anywhere 2s wireless mouse | $129 | $53 | free delivery |

| Valore cordless air duster and vacuum (CL-004) | $74.90 | $35.90 | free delivery |
The Sony headphones sit $1 under the STAY6 threshold. Add a $15 Logitech M190 mouse (was $25) and the $164 basket drops to $158.
What about the haze gear?
The banner shows air purifiers and KN95 and KF94 masks. On our Saturday morning check, the only mask in the collection, a Wistech Kids KN95 box of 10 at $10.71 (was $11.90), was sold out, and Challenger's Acerpure air purifiers were out of stock too. If you need a purifier, our air purifier guide compares the models that are actually on shelves. Seniors aged 60 and above can also collect free masks from the government's second haze-mask wave.
The fine print
- Selected products only. The banner says "sitewide voucher", but the code terms say selected products, so check the cart applies the discount before you pay.
- No cancelling. Orders placed with a promo code cannot be cancelled or amended once Challenger's acknowledgement email arrives.
- While stocks last. Popular lines sell out, and markdowns can end with the campaign.
- One code per order. The terms do not say STAY6 or STAY12 stack with other codes.
- Online only. The codes are for online.challenger.sg, under its usual terms.
Tips
- Check the brand codes first. OPPO100 takes $100 off the OPPO Find X10 series to Wed 28 Oct, and OCTLEN100 takes $100 off selected Lenovo notebooks to Sat 31 Oct. Either beats STAY12.
- Split big orders. Two $300 orders with STAY12 each save $24, while one $600 order saves $12.
- Use the free delivery on small top-ups. Cables, mice and power banks under $60 normally cost you a delivery fee.
- Compare with the anniversary sales. Audio House Hub's 6th Anniversary Sale runs to Wed 4 Nov if you are shopping for big-ticket electronics.
