How to effectively market your product knowing that it has some flaws? Without being deceptive about it

I would be honest to the end users in terms of product flaws because lying to consumers about the product isn't advisable and accetable in sales. In case that the flaws affect the quality of the product,  I would inform the producer and I would simply request the removal of that flaws,or I would require a lower purchase price for the product until the flaw is removed.

The Answer is simple, be truthful and let the customers know the use of it even having flaws.

you can only effectively market your product if one is confident of the product features.otherwise what ever you do will nt get any result .so the question of being deceptive about. Product flaws is thumbs down.

I doubt one can "legally" escape from having to notify the buyer of the flaws, however one technique is to narrow such flaw down and mainly concentrate on the good aspects of the product/service. If your client is overtaken by the good parts of the products, they might turn a blind eye to the rest.

Your product now has some flaws; that we know. Some may give advices related to the difference between "lying about such flaws" (deceiving) and "not mentioning such flaws until asked", as being a less harmful alternative. I can’t advice as such without knowing the type of product, its flows and their effect on the overall "value" of the product to the end customer. Some customers may not mind such "unhidden flaws" if compensated in low price or other extra's (free delivery etc.). The market is full of better, same, cheap, average, expensive, bad, worse and worst products and yet sometimes they don’t seem to go out of business. Where do you wanna be? Do what it takes to make your products meet the customer's demands!

As a rule of thumb, I'd say "don’t deceive your clients about this". Your product now has some flaws, but you don’t want your whole company image to be blacklisted as "deceptive" or "fraudulent", would you?
