There are 182 promotions live in the Australian market as of this week, on the tracker Trevor Services keeps of campaigns as they go to shelf. Twenty-six are gift-with-purchase offers: a bonus accessory pack with a Franke sink, a Visa eGift card with a Beko appliance, complimentary Nespresso capsules, an NRL stubby holder with a bottle of Bundaberg. In not one of them does the shopper contribute a cent towards the gift.
Which is odd, because the self-liquidating premium — where the shopper does chip in — used to be a standard item in the kit. It didn’t die. The supermarkets took it, and most Australian brands who want those economics in 2026 should be buying into a retailer’s continuity programme rather than building their own. The evidence is sitting in a Coles catalogue.
Where the mechanic actually went
Coles ran its Curtis Stone glass container collection from 27 May to 4 August 2026 — one credit per $20 spent, with bonus credits from 23 participating brands including Moccona, Finish, Colgate and Kellogg’s. The redemption table is the interesting part. The 2.2L glass cookware dish was free with 50 credits, or 25 credits plus $25, or $50 outright.
That middle tier is a self-liquidating premium. Proof of purchase plus cash, for merchandise below retail. It is the mechanic exactly, sitting inside something everyone files under loyalty.
Woolworths runs the identical structure. Its Fissler cookware programme prices the 28cm frying pan at 70 credits, or 35 credits plus $35, with the half-credits-half-cash option across the whole range and 19 bonus brands in its second burst alone.
The retailers can run this and a brand cannot, and the reason is structural rather than clever. The supermarket already owns the transaction, the loyalty identity and the checkout. Asking a shopper to top up with cash costs it nothing, because the payment happens inside a flow the shopper is already standing in. A brand running the same offer has to build the identity, the claim and the payment from scratch, then persuade someone to come and use all three.
What is a self-liquidating premium promotion?
A self-liquidating premium promotion is one where the shopper buys the qualifying product, then pays a small additional amount plus proof of purchase to receive a premium item. That payment covers most of what the brand paid to source the premium, so the promotion funds itself instead of coming out of margin. The shopper still comes out ahead, because the item is worth far more at retail than the token price they paid. (The Monash Business School marketing dictionary has the textbook version if you want it.)
Why brands stopped
Not because the arithmetic broke. A discount hands away margin on every unit, including to shoppers who were buying anyway. A self-liquidating premium costs the brand only the gap between wholesale and the token price, and only for people who want the item enough to claim it. On a spreadsheet it is still one of the better trades available.
What changed is the price of asking someone to pay you twice.
The original send-in premium wanted package tops and a cheque in an envelope, which nobody found unreasonable at the time because everything worked that way. The shopper’s baseline now is one tap. Layering a second payment event onto a claim — card details, a separate checkout, a delivery address, a confirmation — is not a small ask. It is a whole payment flow, with its own abandonment rate, its own refund cases and its own support queue.
How is a self-liquidating premium different from a gift with purchase?
In a gift with purchase the brand funds the premium entirely and the shopper gets it free after proving they bought the product. In a self-liquidating premium the shopper pays a token amount towards it, which is what lets the brand offer something of much higher perceived value for the same outlay. The gift with purchase buys you claim volume; the self-liquidating premium buys you a better gift.
Trevor Services has run 63 promotional campaigns, nine of them gift-with-purchase. Every one required a receipt. Not one required a payment. We can name other people’s campaigns here because they are public and ours aren’t, but the volumes are worth having: the largest of the nine, an appliance offer, took 18,584 claims. The smallest, a wine-cabinet premium, took 188. The same dishwasher offer, run three years apart, took 292 claims and then 840 — and that first run had been forecast at 1,000, which is the kind of miss that makes for a quiet meeting. Claim volume on a free premium is already this unpredictable. Put a payment step in front of it and every one of those numbers goes down by an amount nobody can tell you in advance.
So is it worth reviving?
In two situations, with a real cost attached to the first one.
The first is not to build a premium at all, but to get onto the bonus-credit list of a supermarket continuity programme. Those brands are buying self-liquidating premium economics — high perceived value, shopper co-funded — without carrying the build, the payment flow or the claim support.
What you give up is not trivial, and the number that proves the point is the same one that sells it. Twenty-three brands were on the Coles list. You are one logo among twenty-three, quite possibly next to your direct competitor, attached to a premium you did not choose and cannot brand. The shopper’s relationship is with Coles and the data is Flybuys’. You get the economics and none of the asset. Whether that trade is worth it depends entirely on whether you needed the first-party data, and a lot of brands assume they do without ever having used it.
The second situation is when the premium is genuinely aspirational and your shopper already has a reason to come to you: considered purchases, collectable categories, higher ticket prices. Here the trade runs the other way — you keep the data, the branding and the exclusivity, and you pay for them in claim volume.
Two things to hold onto if you go that way. The first is what The Shelf Truth calls the Insult Threshold — the point where the reward stops being worth the effort of claiming it. On a cashback that means the amount is too small. Here it means the premium isn’t obviously worth more than the money and the effort you’re asking for, and a weak premium at a token price is worse than no offer, because the shopper has now priced your gift and found it wanting.
The second is to be clear about the single job you’re giving it. A self-liquidating premium is a basket and loyalty play. It rewards people already committed enough to reach for their wallet a second time, which makes it a poor trial mechanic — you’re asking a stranger to pay you twice before they know whether they like the product. Pick the objective, then pick the mechanic, and accept that a tool this good at one job will be bad at another.
Which leaves the uncomfortable version, for a company that builds promotions for a living. Ask us and we’ll give you a straight answer on which of the two routes your campaign is — but for a lot of brands, the answer is the retailer’s programme, not ours.
