Someone who sells, promotes, or is a general proponent of some valueless or fraudulent cure, remedy, or solution. (Can also be formed as "snake oil saleswoman" if referring to a woman, or "salesperson" to be gender neutral.) 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.
a phrase indicating that no salesman will visit or contact you if you make an inquiry about a product. All inquiries are confidential and no salesman will call.
