The Best Half-Price Household Cleaning Strategy

1. Identify your regular products. What laundry detergent, dishwasher tablets, and cleaning products do you actually use?
2. Check Wednesday weekly. New half-price specials drop every Wednesday at Coles and Woolworths.
3. Buy 3–6 months' supply. Household cleaning products have no expiry concerns. This is the category where stockpiling makes most sense.
4. Don't brand-switch just for specials. If your machine needs a specific formula, stick to it. Switching to save 50% is pointless if you end up rewashing clothes.
5. Watch large pack formats. A 4L bottle of Omo at half price beats a 2L bottle at half price on unit cost every time.
