In 2020 Nutella put a Smeg toaster on the jar. Twenty a day, 1,200 in total, buy a specially marked jar and enter online. Appliance Retailer covered it at the time as a nice bit of Italian-brand matchmaking. Six years later the same pairing is back on shelf as an instant win, and the pack we’re tracking says 1 of 400. Same toaster, same jar, a third of the prizes. We don’t know why the number moved and won’t pretend to. What we do know, from our own campaigns, is that on a small-prize instant win roughly one winner in nine never completes the claim, and that a printed prize count is the one promise a brand can’t quietly walk back.
Because that’s the thing about on-pack instant win promotions that the planning conversation usually skips. Every other mechanic gives you somewhere to hide if the campaign underperforms: you can quietly extend a prize draw, add a bonus week to a cashback, push the creative harder. On-pack, the pack is the contract. The prize count, the odds, the dates, the permit numbers and the entry conditions are all sitting in a warehouse before the first sale, and the shopper can read every one of them. Our argument here is simple: the number you print is not the number you’ll award, and the gap between the two is a design decision most brands make by accident.
What is an on-pack instant win promotion?
An on-pack instant win promotion is a game of chance advertised on the product itself, where the shopper buys the pack, enters by scanning or typing a code from the packaging (or uploading the receipt) and finds out immediately whether they’ve won. The result is decided at the moment of entry by a pre-seeded winning moment, a code allocated a prize before printing, or a 1-in-X trigger. Because the outcome is random it is a trade promotion lottery, and permits are required in NSW, the ACT and South Australia (the Northern Territory in some cases) whenever the promotion is open to residents there.
Two versions are doing most of the work on shelf right now. The first is the code-inside-the-pack model. Victoria Bitter’s current Knock Off Clock promotion is the textbook: buy a specially marked case, find the unique code printed inside it, enter at the microsite. The published terms spell out the rest: ninety pre-determined winning moments for the merchandise prizes, 54,772 instant $20 prizes, one entry per case, five entries per person. The second is the on-pack call-to-action with a receipt or reward-card scan as proof of purchase: the pack does the advertising, the validation happens elsewhere. Of the instant wins on Trevor Services’ own platform over the last couple of years, almost all sit in that second camp. Printed codes are more common in liquor, where the case is big enough to hide one and the retailer is happy to let you.
What the pack locks in before you’ve sold a unit
Packaging lead times mean the artwork is signed off long before launch, and once it’s signed off, several things stop being decisions and start being promises.
The prize count is the obvious one. “1 of 400” is on the label, so 400 it is. On a pack you get a few square centimetres to make the whole promotion feel winnable, and the number you print is the number you’re paying out. If you want to trade a bigger headline prize for fewer small ones, do it before the print run, not after the sales data comes in.
The odds statement is the one that catches people. “1 in 5 wins” is a very different promise from “100 prizes to be won”. A prize count promises a quantity; an odds statement promises a rate. If you print 1 in 5 and your platform seeds winning moments by time rather than by unit, you’ve made a claim you can’t actually control, because winning moments pay out on the clock and sales don’t arrive evenly. Of the 176 live Australian promotions we’re tracking this week, 41 use an instant mechanic, and the liquor ones in particular lean on 1-in-X language: CUB’s game cards at 1 in 5, Jack Daniel’s at 1 in 5, Chivas at 1 in 4. Those campaigns need a code-allocated model, where a fixed share of the codes printed are winners, not a time-seeded one. The odds language and the platform logic are the same decision, and the artwork forces you to make it early. We’ve seen this go wrong in exactly one direction: 1-in-X printed, winning moments underneath, and a very quiet conversation in week three about why the first fortnight’s buyers won at a far better rate than everyone since.
Then there are the conditions the regulator wants on the outside. NSW Fair Trading’s guidance on trade promotions is specific: if a purchase is required to enter, that condition must be clearly and prominently displayed on the outside of the product, any unusual or onerous entry conditions have to be visible without buying anything, and the authority number has to appear on all advertising, which includes the pack. So the permit work has to be finished, not started, before the printer gets the file. Most of the timeline pressure on these campaigns comes from that sequencing rather than from anything difficult about the promotion itself.
How do winning moments work on an on-pack promotion?
A winning moment is a pre-set point in time; the first valid entry received on or after it wins the prize attached to that moment. The moments are generated before launch, spread across the promotional period, and kept secret from everyone including the client. It’s the cleanest way to distribute a known number of prizes across a campaign, and it’s the model behind most of the instant wins Trevor Services runs.
The wrinkle on-pack is that you can’t see your entry curve in advance. If the pack is on a gondola end at Woolworths in week one and back on the regular shelf by week six, week-one entries will swamp the later moments and the back half of the campaign will feel dead to anyone entering. Front-loading the moment schedule to match the expected retail calendar is the fix, and the retail calendar is something to get out of the category manager before you generate the moments, not after. The other wrinkle is stock that outlives the promotion. Promotional packs don’t vanish on the end date, and a shopper who buys one a fortnight later will still try to enter. VB’s terms handle this with a line that valid prize claims in excess of the advertised pool will be honoured, fraud aside. However you handle it, handle it in the terms, because “sorry, closed” arriving after a purchase is exactly the moment a shopper decides your brand is a bit shabby.
Why the number you print isn’t the number you award
Winning is not the same as claiming. The screen says “you’ve won $50”, the email arrives, and a slice of winners never finish. They don’t add bank details, they miss the verification request, they lose the email. On one wine instant win Trevor Services ran over last summer, 227 fifty-dollar prizes were won at the screen and 26 of them, about one in nine, were never claimed and had to be reallocated through an unclaimed-prize tier we’d built into the structure before launch. That’s not an outlier for us; it’s roughly what we plan for on small-prize instant wins with a separate claim step.
On-pack makes this sharper because you’ve printed the number. If the label says 400 toasters and one in nine winners never claims, you’ve awarded around 355 toasters against a public promise of 400. NSW requires the terms to say how unclaimed prizes are dealt with, and defaults to holding a prize for at least three months if they don’t. The standard answer is an unclaimed prize draw after the close, which is what the VB promotion does for its bigger winning-moment prizes. The better answer is to stop the leak: pay small prizes instantly by PayID or issue the eGift card in the same session, so there is no second step to abandon. Every step between “you’ve won” and “it’s in your account” is a place a winner falls out, and for a physical prize like a toaster, where you need an address and a signature, the claim flow deserves as much design attention as the entry form got.
Who runs on-pack instant win promotions in Australia?
Brands usually don’t run these themselves. The pack and the creative come from the brand or its shopper agency; the promotion itself, meaning the entry microsite, code or receipt validation, the winning-moment engine, permits, fraud checks, winner verification and prize payment, is run by a promotional fulfilment platform. Trevor Services is one of those platforms, and the instant wins we’ve run for Grant Burge, Jacob’s Creek and Electrolux are where the one-in-nine figure above comes from. If you’re choosing a platform, our piece on who runs instant win promotions in Australia is the practical checklist, and the permits guide covers the paperwork the pack has to reference. For the other half of the decision, whether an instant win belongs on this pack at all, Bamboo Marketing’s in-store activation and brand activation examples pieces are the ones to read first.
Which brings it back to the toaster. Print 400 on the jar and, on the claim rates we see, somewhere around 355 will make it into a kitchen unless the claim step is designed out before the artwork is locked. The promise on the pack is the only part of an on-pack instant win the shopper ever gets to read, so it’s worth deciding on purpose which number that is. If you’d like to pressure-test a claim flow before print, we’re happy to look at it.
