Oh, a puzzle giveaway! Can't resist a puzzle...
I am a bit late for the fun, but thanks to the discussion of clues up until now I have a bit of a headstart, I guess :)
So, let's see if I can puzzle this out...

And Kudos to grimwerk, of course, for the lovely giveaway!

I didn't know that either. With that knowledge maybe I'll take another crack.

Thanks!
I have all the right answers (confirmed) but still haven't puzzled out the relationship. Knowing now the keys are hexidecimal might help.

But I still haven't puzzled out why the difference between 'exposition' and 'exhibition' is relevant, so I'm guessing it may still elude me.

Yeah! I figured it out... Oh, that sweet sweet feeling of a puzzle being solved :)
That was quite a brain teaser! In hindsight, the solution seems so simple, but actually getting there...

I haven't redeemed the game, mind you, I feel kind of bad sneeking in "through the backdoor" and snatching the price...

Actually, those hints (while I'm sure they were well intentioned) totally sent me on a wild goose chase... So, if anyone is still having a go at this puzzle, do not start comparing words back and forth, it will get you absolutely nowhere ;)

Well done, Hobgoblin!

That was quite quick.

It seems the puzzle is still up in the air!

I can't figure out some of them! :-(

The only NATO codes I can discover are the phonetic alphabet and the flags.

Also, "if not p then not q", as far as I know, is the same as "if q then p". In English, the name I found was "Transposition", which has too many letters.

Any more tips?

Exactly!

If p then q is the default expression when learning [propositional] logic. (Well, for me, in 1980something!)
If not p then not q is the _______ of that expression.

If you wish, you can solve both by googling grimwerk's clues exactly as is and looking through the first few results.

haha
Maybe all my clues!
And it may be that google autocomplete handles most of them.

My next puzzle will be somewhat google-resistant.

edit:
Although, google results vary by user history and region. So maybe I'm wrong.

Well, I'm not sure I could have figured out the Speed Stick thing by myself...
As for the other clues, I think google is definitely a good friend there :)

That Speed Stick nonsense was a brief (and probably offensive) internet phenomenon. I was expecting those unfamiliar to fall back on google, so I hope it works everywhere. Still, in our home, "It's not expensive." is code for "You should probably take a shower." So everyone is obliged to endure my stupid clue.

I had to google that one. Most Speed-Stick is anti-perspirant, so at first I thought the answer you were pointing to was "deodorant" which fit the letter count.

Though the more I thought about it, while not all deodorants are anti-perspirants, anti-perspirants generally also are deodorants. And speed-stick sells both in any case ;)

Curious if the first element of the code is a 'B'

I'm afraid not.

Back to square one then. ;)

I'd tried summing the letters of each word (a=1, etc.) then taking the remainder dividing by 16 and converting the result to hexadecimal.

It's a lot simpler than that. Don't give up.
