A more accurate term to describe the art of "Salesmanship".
As selling people things in our consumer culture is about wants, not needs; appealing to ego and
irrational desires, not demonstrating the long-term value of owning
the product.
Salesmanipulationship is about deceit, coercion, and putting someone into a
pressure-cooker so they are unable to think critically on what they are about to do.
A woman went into
the shop to buy a $50 black dress, she came out not only with
the dress but with nearly $60 in
accessories for it, thanks to the clerk's Salesmanipulationship.
