Key Takeaways
- Nobody plans to buy a bag of chips. 62 percent of salty snack purchases and 63 percent of candy purchases in convenience stores are unplanned (NACS shopper research, 2025).
- If six in ten sales are decided at the shelf, the shelf is doing the selling. A set with gaps in it loses sales that were never planned and won’t be recovered.
- Cravings drive unplanned buys far more than discounts do. 65.5 percent come down to wanting something in the moment, against 51.3 percent for a deal.
- Bags and pouches are the worst-behaved packaging in the store. They slump, lean, and settle in a way boxed goods don’t.
- On impulse categories, facings beat depth. A customer can only buy what they can see.
Nobody walks into a store planning to buy a bag of chips.
That sounds obvious until you look at what it means for the shelf. NACS shopper research puts unplanned purchases at 62 percent for salty snacks and 63 percent for candy. Baked goods run 53 percent.
So, for roughly six in ten sales in these categories, the decision happens right there at the shelf. Nothing before that moment influenced it: no list, no plan, no brand loyalty carried through the door.
Which makes the shelf itself the thing doing the selling. And snack and confectionery sets happen to be the fastest-collapsing shelves in the entire store.
What the impulse numbers actually tell you
There’s a second set of figures here that changes how you approach it.
When NACS asked why unplanned purchases happen, the top answer was a personal craving in the moment, at 65.5 percent. Discounts came second at 51.3 percent. Something catching the eye came third at 46.6 percent.
That ordering matters. The craving is already there. You’re not creating demand with a price cut; you’re intercepting a decision that’s mostly been made by the time someone’s standing in the aisle.
What the shelf has to do is be the obvious place to satisfy it, which means being visible, being complete, and being easy to choose from.
A gap in an impulse set is worse than any other gap in the store. If someone came in for milk and the milk’s out, they’ll ask or come back. If someone half-wanted a snack and the set looks picked over, they don’t buy one. There’s no follow-up, no substitution, no second visit. The sale never existed.
Snack packaging is the worst-behaved in the store.
Every category’s got a packaging problem. This one’s got all of them at once.
Bags don’t stand up. A flexible bag is mostly air with the product settled in the bottom. It leans, it slumps forward onto its face, and once one goes, the two on either side follow.
Pouches settle. Stand-up pouches hold their shape when full and lose it as product shifts. A row that was square at 9 am has sagged by midday without anyone touching it.
Boxed confectionery stacks unevenly. Small boxes are light enough that pulling one from the middle disturbs the whole row rather than leaving a clean gap.
And the units are small. A single missing facing in a snack set is proportionally a much bigger hole than a missing facing in a category with large packaging. Three gone from a row of six reads as empty.
Put those together, and you’ve got a category that needs facing more than any other, in a store where nobody’s got time to face anything.
Facings beat depth here.
This is the allocation decision most stores get wrong on snacks.
The instinct is to load depth. Six bags deep across three lanes means fewer restocks, which feels efficient. Trouble is, only three products are visible, and in an impulse category, visibility is the whole game.
Six narrow lanes, three deep, hold the same total stock and show twice as many choices. For a shopper acting on a craving rather than a plan, that doubles the chance that something in front of them is what they want.
There’s a limit, obviously. Cut lanes too narrow, and you’re constantly restocking, so you’ve swapped one problem for another. But most snack sets are deeper than they need to be, and the back half of a deep lane is doing nothing except waiting.
Worth checking where your growth is when you reallocate. Alternative snacks grew 7.9 percent in 2025, faster than the convenience store category overall, largely driven by protein demand. A set laid out three years ago probably isn’t giving it space proportional to what it’s selling now.
Where these categories belong
Snacks and confectionery operate in two places, and most stores use only one of them properly.
The main set is where people go when they’ve decided they want something and are choosing what to get. It needs range and clarity. This is where facings matter most.
The impulse positions are where people encounter the category without seeking it out. The queue line, the counter, and the path between the door and the cooler. These need very few SKUs and absolute tidiness, because a cluttered secondary display reads as noise and gets skipped entirely.
The mistake is treating a secondary position like a shrunken version of the main set. Eight products at the register are a jumble. Three products at the register is a decision.
Worth remembering who’s walking past. Around 49 percent of convenience shoppers are what NACS calls Time Optimizers, people who want in and out quickly. They’re not going to study a crowded counter display. They’ll grab something obvious or nothing at all.
Keeping the set faced without adding hours
The honest problem with everything above is that it assumes somebody’s maintaining it.
A snack set needs to face more than any other category, and it competes for the same staff time as everything else. In practice, it gets done in the morning and drifts for the rest of the day. So most customers see the drifted version rather than the tidy one.
Two things help.
Lane separation, so bags can’t lean into each other. Half of what looks like a facing problem in a snack set isn’t one. It’s a lane problem. Product hasn’t gone backward, it’s gone sideways, and one tipped bag takes its neighbors with it.
Constant forward pressure, so the row advances as it sells rather than waiting for someone to pull it forward. Flexible bags and small boxes are exactly the right packaging for this. There’s a separate piece on how shelf pushers work and where they belong if you want the details.
Neither is expensive. Both remove work rather than adding it, and that’s the only kind of merchandising change that survives a busy week.
The short version
Six in ten snack and candy sales are decided at the shelf, so presentation isn’t just cosmetic here. It’s the mechanism.
The packaging in these categories is the least cooperative in the store, and the sets collapse faster than anything else. Go wider rather than deeper, because facings sell impulse and depth doesn’t. Keep secondary displays short rather than full. And fix the drift mechanically rather than scheduling more facing time, because the schedule is the first thing to go on a busy day.
Frequently asked questions
What percentage of snack purchases are impulse buys?
NACS shopper research puts unplanned purchases at 62 percent for salty snacks and 63 percent for candy in convenience stores. Baked goods run 53 percent.
How do you stop snack bags from falling over on a shelf?
Lane separation does most of the work because bags usually fall sideways before they fall forward. Adding constant forward pressure behind the row handles the rest, since flexible packaging doesn’t hold position once the product starts settling.
Should snack shelves be deep or wide?
Wide, in most cases. Impulse categories sell on visibility, so more facings beat more depth per facing. The same total stock in narrower lanes shows a shopper twice as many options.
Where should snacks be placed in a convenience store?
In two places. A main set with a proper range where people choose, and a small, tight secondary position near the register or along the main walking route, where people encounter the category without looking for it. Keep the secondary position to very few products.
Do discounts drive impulse snack sales?
Less than most operators assume. NACS research found that 65.5 percent of unplanned purchases were driven by a craving in the moment, compared with 51.3 percent citing a sale or discount. The demand tends to exist already, so the shelf’s job is to be the obvious place to satisfy it.
