Affiliate Marketing Secrets

Selling a product what are the benifits of POA?
I have sold cars for 10 years and been in sales all my life and understand might make the phone ring and you can collect interested people’s contact details and call them back if it was reduced if it did t sell within a certain time
I’m my opinion the secret of selling is to “offer it” (that includes the price)
If I see £POA I automaticity assume the product is too dear or I cannot afford it. I personally would never use POA as I would expect people either Curious or have no idea about current market values of the product. Thus wasting both of our time
Has anyone had success or unsucess with POA??
or changed to the real price???
I am asking this question as my partner just called (21.37) a Horsebox advertisement (POA to Surprise surprise ask THE PRICE!). The seller said his wife would call back in 45 mins (as she was out) to discuss the elusive price
After putting the phone down my parter said “it’ll be too expensive” I asked Why did you even ring???
Surely POA causes more problems than it solves. Your thoughts?
