Packing a Punch: The Power of Divisible Pricing in Multipacks

"Do I really need that much toilet paper?"

If you’ve ever shopped at a big-box warehouse, you’ve probably questioned whether you’ll actually use up those jumbo packs of toilet paper, deodorant, or air freshener. The sheer volume can make single-item purchases at a local store seem more practical. But a recent study suggests that a simple shift in bulk pricing could make buying in bulk feel like the smarter option.

As convenience and bulk shopping grow in popularity, understanding what drives our buying choices is crucial. This new research uncovers a surprising insight that could transform how brands price multipacks to make them more appealing.

What is the "Price Divisibility Effect”?

The "Price Divisibility Effect" is a concept studied by researchers Hanyong Park, Jaehwan Kwon, and Rajesh Bagchi, which shows that consumers are more likely to buy a multipack when its total price is easily divisible by the number of items it contains. This means that a four-pack of body wash priced at $16 (making each unit $4) is more attractive to shoppers than the same four-pack priced at $15.30, even though the latter is cheaper. The ease of dividing the total price by the number of items seems to make the purchase feel simpler and more justifiable.

Perception is Key: Why Divisibility Matters

Divisible pricing encourages consumers to see each item as a separate, quickly used unit, eliminating questions like “How long will it take me to use all this?” or “Do I really need so many?” This pricing approach makes it easy for shoppers to understand the cost per item, making each item feel like it will be used up sooner. This sense of “quick use” makes buying the whole pack seem more worthwhile and helps justify the purchase of multiple items. Essentially, divisible pricing simplifies mental math, creating a feeling of “quick consumption” that leads to a higher likelihood of purchase.

• For instance, pricing a 4-pack at $16 instead of $15.30 can make it more attractive, even if the cost per unit is slightly higher. This tactic works well for items like toiletries, snacks, and beverages, encouraging shoppers to buy in bulk.
• Highlight Per-Unit Value in Marketing: Emphasizing the per-unit cost rather than the total pack price can further enhance the appeal of multipacks. This strategy helps customers focus on the value of each item and makes the purchase feel more worthwhile and consumable.
• Extend the Principle to Bulk Products: While especially effective for multipacks, this approach can also apply to bulk sales of single items (like wholesale groceries). Retailers can use divisible amounts (e.g., “10 lbs for $10”) to make the math simple, encouraging shoppers to purchase larger quantities.

These insights offer a simple yet effective way for retailers to make multipacks and bulk products more enticing. By pricing with easily divisible numbers, brands can help customers better “organize” their purchases in their minds, boosting sales without relying solely on discounts. So, next time you’re setting prices or shopping in bulk, remember that sometimes, it’s not just about the total cost – but how easily we can make sense of it!
