Why the 'Bigger' Package Wasn't Actually the Better Deal
A larger package doesn't automatically have a lower price per unit — pricing strategy, packaging costs, and promotional pricing on a specific size can all mean a smaller package has a better (or equal) unit price than a larger one, which is exactly why calculating and comparing the actual unit price, rather than assuming bigger is always cheaper, matters.
"Buy the bigger size, it's always cheaper per unit" is common advice, but it's not a guaranteed rule — checking the actual math sometimes reveals the opposite.
Why bulk pricing isn't guaranteed
While it's common for larger packages to offer a better unit price (economies of scale in packaging and distribution), it isn't a guarantee — a retailer's specific pricing strategy for a given product line, a promotional discount on a smaller size, or simple pricing inconsistency can all produce a larger package with an equal or even worse unit price.
A worked example where smaller wins
A small 8 oz package on sale for $2.00 works out to $0.25/oz. A regular-priced large 32 oz package for $9.60 works out to $0.30/oz — the smaller package, boosted by a temporary sale, actually has the better unit price here, despite the larger package's usual bulk-pricing advantage.
The habit that catches this
Checking the actual unit price (often printed on the shelf tag, or easy to calculate directly) rather than assuming the larger size is automatically the better deal catches these situations — a small habit that occasionally reveals a genuinely different, non-obvious answer.
