How Coles and Woolworths half price specials actually work
If you shop at Coles or Woolworths you have probably noticed that the block of chocolate you bought at half price in March is at half price again in June, and that the shampoo you paid full price for last week is suddenly $8 cheaper. That is not luck. Australian supermarket promotions run on a cycle, and the cycle is regular enough to plan around.
The weekly rhythm
Both Coles and Woolworths change their specials on a Wednesday. The new catalogue takes effect that morning and runs through until close of trade the following Tuesday. That means:
- Wednesday is the day the new half price lines appear.
- Tuesday is the last day to buy anything from the outgoing week at the promotional price.
- A product that appears on Wednesday and sells out by Friday is simply gone — promotional stock is allocated in advance and is not always replenished mid-week.
This is why shopping on a Wednesday or Thursday tends to produce better results than shopping on a Sunday. The popular half price lines — nappies, coffee, laundry powder, well-known chocolate brands — are the first things to clear.
Half price is not the only kind of discount
This is the part that costs people the most money, because the different promotion types are presented with almost identical visual weight in-store and in the app.
| What you see | Where | What it actually means |
|---|---|---|
| ½ Price | Both | A genuine weekly special at roughly 50% of the stated regular price. Ends with the catalogue. |
| Down Down | Coles | A longer-term price reduction, not a weekly special. The price is lower than it was, but it has often been at that level for months and may stay there. There is no urgency. |
| Prices Dropped | Woolworths | The equivalent of Down Down — a sustained lower price rather than a one-week deal. |
| Low Price Always | Woolworths | An everyday-low-price line. Not a discount at all, just a claim about the base price. |
| Member price / card price | Both | Only applies if you scan Flybuys (Coles) or Everyday Rewards (Woolworths). Without the card you pay the full price at the register. |
| 2 for $X | Both | A multi-buy. Sometimes excellent, sometimes barely below the single-unit price. Always check the per-unit maths. |
Only the first row is what most people mean when they say "it's on special". The rest are worth knowing about, but they do not reward the same behaviour — there is no point stockpiling a Down Down item, because the price is not going back up next Wednesday.
The rotation cycle
Supermarkets negotiate promotional slots with suppliers well in advance. A brand pays for — or funds through a trade deal — a period of prominent promotion, and in return gets the volume that comes with a half price week. Because there are a limited number of slots and a large number of brands competing for them, individual products come round on a rotation.
In practice, a well-known packaged grocery line tends to reappear at half price every six to ten weeks. Competing brands in the same category are usually staggered, so if brand A is half price this week, brand B will often be half price a few weeks later. That has two practical consequences:
- If you are not brand-loyal, you rarely need to pay full price for a category at all. Something in "laundry liquid" or "instant coffee" is nearly always on promotion; you just have to be willing to take whichever brand is up this week.
- If you are brand-loyal, buy enough to reach the next cycle. When your brand comes round, buying two months' worth is not hoarding, it is simply matching your purchase to the promotional period.
Why the "was" price matters
Under Australian Consumer Law, a "was/now" claim must not be misleading — the crossed-out price is supposed to represent a price the product genuinely sold at for a reasonable period beforehand. The ACCC has taken action against retailers over exactly this issue in the past, so the major chains are generally careful about it.
That said, "not misleading" is a lower bar than "the best price available". A product can be genuinely half price against its own recommended retail price and still be more expensive per 100g than a rival brand at full price. The regular price is a fact about that one product's history, not a statement about the market. This is what unit pricing is for, and it is covered in our guide to reading a unit price.
How to actually use the cycle
- Write down the fifteen things you always buy. Not a shopping list — the products that appear on every second receipt. For most households it is a surprisingly short list.
- Check those fifteen against the new specials each Wednesday. That takes about two minutes if the deals are in one place, which is the whole reason this site exists.
- When one comes up, buy through to the next cycle — roughly two months' worth, if the product keeps and you have somewhere to put it.
- Ignore everything else. The single biggest way to lose money on specials is buying discounted things you would not otherwise have bought. A 50% discount on something you did not need is a 100% waste.
The one-line version: specials change Wednesday, half price is different from Down Down and Prices Dropped, most products come back around every six to ten weeks, and the money is made by buying your regular items in the week they are cheap — not by buying new things because they are cheap.
What about the loyalty programs?
Flybuys and Everyday Rewards both layer member-only pricing on top of the public catalogue, and both run personalised offers based on your purchase history. They are worth joining because they cost nothing, but treat them as a small bonus rather than a strategy. The points economics on both programs are modest, and a personalised offer is designed to change your behaviour — usually by getting you to buy a category you do not currently buy from that chain.
The base half price catalogue, which is what this site tracks, is available to everyone without a card.
