If the price is good, I would assume customers will jump in and buy, they may even schedule their buy to align with this day, to celebrate this day or not doesn't matter imho.

For many countries, November 11 is 'Armistice Day', 'Remembrance Day', Veteran's Day, or some other day remembering those fallen in war and as such would probably take offense at any attempt to commercialise or cash-in on such a day.

I can't tell whether or not you're being sarcastic but in the US, Veteran's day usually means a major sales holiday not unlike Labor Day, Memorial Day, or Black Friday.

Ok. Interesting to know that. I wasn't being sarcastic. In Australia at least you'll still get a minute silence at 11am with schools and most work places stopping to commemorate it (it's not a public holiday).
