tonykay and lilmsmaggie nailed it! Point, set, and match in tennis jingo.
The OP's expressed characterization of Amazon's sales price for the unit as "pure greed" is just his extreme biased anecdotal and personal value judgement . To AMAZON its just simple business and sales marketing triggering a Hobson's Choice.
A Hobson's choice is a free choice in which only one thing is offered. Because a person may refuse to accept what is offered, the two options are taking it or taking nothing. In other words, one may "take it or leave it". The phrase is said to have originated with Thomas Hobson (1544–1631), a livery stable owner in Cambridge, England, who offered customers the choice of either taking the horse in his stall nearest to the door or taking none at all.
