Q: If my competitor has a superior product than mine or offers a better price, can I try to convince a potential customer to buy from me despite the superiority of my competitor’s offer?

A: A seller is allowed to mention the positive aspects of his product in order to drive the sale, provided he does not mislead or misinform the customer. For example, he can enumerate all the positive aspects of his product or say that the price is a good one, but he cannot falsely state that he is offering the top-rated brand or the best price in the area.

It is only considered misleading the buyer if there is some element of falsehood or false impression in his sales pitch. If the customer decides to buy based on truthful statements of the seller without investigating the matter further, that sale is halachically permitted.

Furthermore, we can assume that the consumer entered the store or read the advertisement with the clear understanding that the seller will try to convince him to buy his product.
