BWS is running a Jacob’s Creek prize draw with a $50,000 top prize while the retail media network beside it sells the same shelf by the CPM. Two different jobs, bought from the same retailer, in the same aisle, at the same time. One rents you an audience for the flight. The other leaves you a list of people who put their hand up and a mechanic you can run again next quarter. That difference is the whole argument, and it’s why the “is retail media worth it” question is framed wrong before anyone answers it.
The honest position: retail media and a promotion do different work, so comparing them on “worth it” is a category error. A small agency’s money is better spent on a mechanic that generates first-party entry data it owns, because retail media rents an audience you never keep.
Is retail media worth it for small agencies versus larger brands in Australia?
For a small agency, usually not as the main spend — retail media buys reach you rent for a flight, then return. A purchase-gated promotion built into the same retailer buy earns backing and leaves you an owned entrant list. Larger brands can run both; smaller ones should lead with the mechanic that banks data.
Why the budget keeps flowing to the retailer’s network
There’s a real gravity here, and it’s worth naming before arguing with it. Australian retail media is a serious market now — the IAB Australia reports most networks grew onsite and offsite revenue through the reset year, and Mi3 sizes it around a $3bn market set for roughly 50 per cent more inventory as Australia Post and Amazon pile in. When the channel is adding that much shelf, it dominates the budget conversation by sheer presence. The retailer wants your money there, the deck is ready, and the shopper is genuinely in that environment — retail trade turnover, which the ABS measures monthly, is the denominator both the network and the promotion are chasing.
So the pull is understandable. The problem is what you have at the end of the flight. Buy a CPM, defend share for the window, and the quarter closes with a media report and no entrants. You rented reach at scale and handed the audience relationship straight back to the retailer, who keeps the data because it’s their network.
The counter-position: isn’t it just pay-to-play now?
Here’s the strongest version of the other side, stated fairly. Retail media is where the shopper actually is, and where the retailer wants the investment. A small brand that can’t fund a Cartology-scale buy can’t compete for attention in that environment — so it’s pay-to-play or stay off-shelf, and the mechanic argument is a nice idea for brands that already have range.
Half of that is true. You do need to be present where the decision happens, and a tiny brand won’t out-spend a category leader on offsite inventory. But “present” and “renting the whole aisle” aren’t the same spend. A purchase-to-enter promotion is itself a reason the retailer gives you support — the mechanic moves units off their shelf, which is the thing that earns retailer backing that a paid placement alone doesn’t buy. You’re not choosing between visibility and nothing. You’re choosing between visibility you rent and visibility you partly earn by giving the retailer a sell-through reason.
Where the mechanic wins on the budget maths
This is the part a CPM can’t match: a cashback doesn’t cost its headline, because of slippage — the share who buy, qualify and never claim. Retail media spend is fixed the moment you book it. A cashback’s true cost is the claimed portion, which is always less than the budgeted ceiling, so the money you don’t pay out stays yours. That’s a structurally different budget line, and it’s one of the levers behind the cashback-or-prize-draw decision rather than a reason to always pick one.
The scale play is visible right now in liquor. Vinarchy is running the BWS Jacob’s Creek draw at $50,000 and a Grant Burge AFL experience at $15,000 — big national draws with big prizes. A small agency can’t fund that top line. But a $3,000 draw collects the same kind of first-party entry — name, email, consent, purchase proof — as the $50,000 one. The data structure doesn’t scale with the prize. What scales is the entry volume, and even that follows friction and relevance more than headline value, which is the quieter finding in whether a bigger prize pool gets more entries.
The reusable part is the real asset. Retail media evaporates when the flight ends; an entrant list and a proven mechanic are things you run again, which is why reusing a mechanic is a strategy and not a shortcut. A sibling view of how all this sits inside the aisle decision is covered in Bamboo Marketing’s work on in-store marketing strategy.
None of this says switch the whole budget off the network. A larger brand defending category share has the room to run paid reach and a data-generating mechanic side by side. The call that matters for a smaller agency is sequence and proportion: lead with the thing you keep, use the network to amplify it, not the other way around.
Retail media rents you the aisle for a flight; a promotion leaves you an entrant list and a mechanic you can run again, which is the part a small agency can actually own.
If you’re weighing network spend against a data-generating mechanic, we’d be happy to talk it through.
