Selling you X widgets for Y dollars -- we both agree to those amounts -- is not fraud. And it's still not fraud no matter what I sold widgets to someone else for. It's just a negotiated, voluntary contract.
Offering discounts to one guy and not another? Not fraud. Just a style of capitalism some people get offended by (hence one might want to not mention it).
The US Government being a chump that's bad at negotiating to get stuff cheaply? Not fraud (excepting politicians who made campaign promises to do better with no reasonable expectation of being able to do better ;)
