Frequently Asked Questions
Is the larger bulk package always the cheaper unit price?↓
Not always. While bulk buying frequently saves money, supermarkets frequently place popular "family sizes" at a higher unit cost than standard packages, knowing shoppers assume bulk is always cheaper.
What is retail shrinkflation?↓
Shrinkflation occurs when manufacturers subtly reduce package volume or item count while maintaining the same shelf price, raising the unit price without alerting casual shoppers.
How does unit pricing help commercial procurement?↓
Commercial buyers use unit pricing to compare vendor bids across non-standard packaging (e.g. 50-lb sacks vs 20-kg boxes) to negotiate optimal volume contracts.
Are unit price labels legally mandated in retail stores?↓
In many US states and European countries, retail supermarkets are legally mandated to display unit prices (cost per ounce or gram) on shelf tags alongside total price.
