Business Halacha Daily

Ona’ah in Today’s Working Environment

Ona’ah is classically defined as when an item is priced above 1/6th more than the market price. We all get annoyed when we feel we get overcharged for an item, however there are a myriad of factors that go into pricing an item, such as quality, service, location and more which would justify the higher pricing. How then can we apply ona’ah in contemporary times?

Ona’ah in Supermarkets

In the grocery store where I typically shop, a bottle of milk costs $3. I went to another store today and saw they are selling the same bottle of milk for $4. Is that ona’ah ?

Onaah in Discount Markets

In Manhattan, it is very common for street vendors to sell knockoffs of name brands. If someone buys a belt from a street merchant that is claimed to be Ferragamo but is clearly an imitation for $50, and then a block further, sees another vendor selling the same counterfeit Ferragamo for $30, would he have a claim of onaah ? Answers: It stands to reason that there is a legitimate market price for knockoffs. We know there are different prices for a product that is a brand name and one that is generic. There certainly is a market for generic products, with the accepted market price being less than the cost of the same product with a brand name. It would seem that the same idea would apply to knockoffs. If the item is being sold illegally, that might make it difficult to pin down what the price is; but if there is a clear price as to how much this knockoff sells for everywhere in Manhattan, that would become the accepted price and overcharging would be onaah . Question: Knockoffs are often inferior in quality. If someone would buy an imitation Ferragamo belt and then it subsequently breaks the first time he tries it on, would he have a claim of mekach ta’os or do we say that he should have known it might not be good quality?
