Half price health and beauty: the category worth watching most

In almost any given week, health and beauty is the largest half price category in both Coles and Woolworths. It is also where the individual dollar savings are largest, and where a small amount of planning produces the most obvious result on a receipt.

Why this category is discounted so heavily

Three things stack up:

• High margins. The gap between what a bottle of shampoo costs to make and what it sells for is much wider than for a tin of tomatoes. There is simply more room to discount.
• Recommended retail prices set high. Cosmetics and skincare are priced against an RRP that reflects pharmacy and department store positioning. A supermarket selling at 50% of that number is still often making an acceptable margin.
• Brand competition. Consumers switch haircare and skincare brands readily, so brands buy promotional slots aggressively to capture trial. That funding is what pays for the discount.

The net effect is that a half price week in this category is a real reduction against a price you might genuinely have paid, in a way that is less true in, say, packaged pasta.

What is worth buying in quantity

Excellent

• Razor blades and cartridges. Extremely expensive per unit, never expire, take almost no space. The clearest buy-in-bulk item in the entire supermarket.
• Electric toothbrush heads. Same logic. A pack at half price is a genuinely large saving.
• Deodorant and antiperspirant. Keeps for years, used at a predictable rate.
• Shampoo, conditioner and body wash. Sealed bottles are stable for a long time. Buy three to six months of the one you use.
• Toothpaste and floss. Long dated and constantly promoted.
• Feminine hygiene products. No expiry concerns, entirely predictable consumption, frequently discounted.

Good, with a date check

• Vitamins and supplements. Heavily discounted and worth buying ahead — but read the expiry. This is a category where deep discounts sometimes reflect a batch approaching its date, and a large tub you will take a year to finish needs a date well beyond that.
• Sunscreen. The most important date in the category. Active ingredients degrade over time and with heat, and an expired sunscreen does not deliver its stated SPF. Buy enough for a season, not for a decade, and do not leave it in a hot car for months.
• Pain relief and pharmacy lines. Long shelf lives, but check the date and be sensible about the quantity you keep at home.

Buy one, not six

• Skincare with active ingredients. Retinol, vitamin C serums and similar products degrade once opened and are sensitive to light and air. An unopened backup is fine; a shelf of them is not.
• Anything you have not used before. This category has the highest rate of "bought it on special, did not like it, never finished it" of any part of the shop. Skin reacts differently to different formulations, and a half price discount is not worth four bottles of something that irritates you.
• Cosmetics in a shade you have not tested. Foundation and concealer especially.
• Fragrance. Keeps well, but it is a personal enough purchase that buying multiples of something untried rarely makes sense.

The PAO symbol

Most cosmetics and skincare carry a small open-jar symbol with a number inside — 6M, 12M, 24M. That is the "period after opening": how long the manufacturer says the product remains good once you break the seal. It is separate from any printed expiry date, which applies to the unopened product.

This is the number that determines how much is sensible to buy. A 12M product that you use up in three months means you can comfortably hold four; a 6M product you use slowly means one.

Supermarket versus pharmacy pricing

For the specific brands supermarkets stock, a half price supermarket promotion is usually very competitive with a discount pharmacy's ordinary price, and sometimes better. Where pharmacies win is range: they carry professional and dermatological brands supermarkets do not, and they run their own promotional cycles on those.

If you use a mainstream mass-market brand, watching the supermarket half price cycle is generally the cheapest route. If you use something more specialised, it will rarely appear in a supermarket catalogue at all.

A note on what "half price" means here specifically

In this category more than any other, the crossed-out price reflects a recommended retail price rather than a price customers routinely pay. That does not make the discount fake — it is a real reduction against the supermarket's own regular shelf price — but it does mean the percentage overstates how unusual the final price is. Some products in this category are on some kind of promotion most of the time.

The practical response is the same as everywhere else: judge the deal on the dollar figure and the unit price, not the percentage. There is more on this in how to read a unit price.
