Amazing Salesman Discounts

In our vast experience we have become extremely aware of some quite ridiculous ploys made by salesmen who often spend several hours to try & pressure sell their products. They generally begin with an obscene price, which in all honesty is an initial con, to then reduce it to sometimes as much as a third of their original quotation.

How is this not attempted theft?

We do not understand how this practice is legal and furthermore how some commission paid sales individuals believe it to be acceptable to attempt to quite literally con innocent people of their hard earned cash.
