Did you just publish the result of a benchmark or performance comparison test you ran to establish the difference in $/performance ratio between competitors?
If so, I have bad news for your license compliance...
That's a good thing to warn people of, but feels like a complete red flag in a license. If a company isn't willing to stand by their product in reviews, then that should be a reason to disqualify their product from consideration.

And you can get pricing from any VARs website such as CDW.com
Good try though.
