Familiarity adds another layer. A customer who purchases the same product repeatedly may eventually stop reading the front and back of the package every time.
The shape, brand colors, and location on the shelf become enough to identify it. If the package remains visually similar, shoppers may naturally expect the quantity to remain similar as well. This expectation is particularly understandable for products purchased weekly or monthly. The greater the familiarity, the easier it becomes to shop automatically.
That does not mean a manufacturer is necessarily doing anything improper whenever the quantity changes. Companies regularly adjust package sizes for many reasons, including production costs, transportation, product reformulation, manufacturing equipment, customer demand, and retail strategy. A smaller package can still be perfectly legitimate if required labeling accurately states its contents and the overall presentation complies with applicable law. The problem arises when the package creates a materially misleading impression about what is actually being sold. Whether a specific design crosses that legal line depends on facts, jurisdiction, and the regulations governing the product.
