Ads like this I think of more like a ploy to raise the prices of other sales of the same machine. That somewhat overpriced XYZ pin that's been sitting on the pinside market for months suddenly looks like a steal when ads like this show up. Enough ads like this and any casual consumer that does a price check will think that's a normal price, over time raising the price of all of them. The tactic must work since people keep doing it.
