Jesus, are you serious? The question isn't why would you, as much as it's why would you put that here, and in that manner? Your customer service reputation is horrid, business must be pretty good though. Especially since you seem content to place shady intentions like this for all to see. Either way, I have heard some good things about you guys too, so maybe it all evens out. This remark just seems wrong to me.
Why is this shady? Your the one who's shady if you think a vendor shouldn't be informed of a possible pricing error on their site. It doesn't sound like anyone here has an honest interest at heart, just their own. Finding ways to get the lowest price regardless of how it's done.
