Can good communication sell a bad product?

Yes... Talented sales man can definitely sell a bad product by using his/her communication skills. It will be a very short term gain. The moment customer realise the quality of a product, then the company or a sales person will loose credibility.

Unfortunately, yes it can. However a bad product generally proves to be successful only in the short run.

Yes, Mostly time.....it all depends upon the sales person's abilities or negotiation and how clever is he/she...

Yes through good cumunication we can sell anything but after that we will lost that customer. Bcz after that never he will come again to that store to buy anything.

In my experience there is no bad or good product, only matter demand we living in the world where commudity like sand to gold are in demand, only maters right knowledge, pitch, market and price.   

The good communicating sales person can sell degraded product to his customer and this depend also on the customer knowledge of the product

Sell have easy and hard dont have bad and good

Yes, he can sell a bad products depends on his skills, we call that "the man who can sell the air" But that will be short term relationship not long term

Yes, it can....however it will reflect negativly on the related brand equity at near future,

Selling a products (whatever it is) depend on some factores , one of them is how to communicate your products to customers depending on customer profile....
