There’s always going to be someone who buys something a few weeks or days before a sale starts - that’s life.
Given that Black Friday is now ‘a thing’ in the UK, I could’ve guessed that there’d be a sale of some of the third party add-ons and therefore could’ve waited to see if this was going to be reduced, but I wanted it NOW! 
I therefore bought the BN2T at full price and have been happily flying it for the last fortnight on my Xbox and don’t regret the purchase at all. Given how much I know I’ll be flying it in the future, the cost per hour is going to be negligible in the long run, like all the other aircraft from Blackbox - great value, even at full price!
