snake oil salesman
Someone who sells, promotes, or is a general proponent of some valueless or fraudulent cure, remedy, or solution. (Can also be formed as "saleswoman" or "salesperson.") I find it hard to believe anyone would fall for those snake oil salesmen on TV selling holistic medicines and therapies. A lot of people have been swayed by the presidential candidate's plan for economic growth, but if you ask me, she sounds like a snake oil saleswoman.
no salesman will call
An assurance that, after an inquiry has been made about the price of something, no one will make direct contact to follow up and try to secure a sale. Our agents are always ready to give you a quotation on the insurance policy that is right for you. If you decide afterward that now isn't the right time, no salesmen will call, so there's absolutely no pressure to sign up.
