There are several spots where you have spelled it PUGB instead of PUBG. Just go ahead and delete my comment when it's fixed. Hate being the guy pointing out mistakes but I figure I would want to know. Lol
Well the philanthropy is noble, but if I want to donate to charity or contribute to one, I want to be able to claim it on taxes. I won't be able to do that if I buy this case vs. donating direct to a 501(c) non-profit charity. That is even if this charity they support is qualified as falling under that IRS code.
Not everyone cares about potential tax write-offs, and $20 (assumed: 10% of MSRP, $200) isn't going to really make any scratches in tax breaks anyway.
Some will feel its a way to do a "good deed."
Some won't care whether a percentage goes to any charity at all.
Some will grab it just because of the PUBG branding, regardless of performance.
If I was in the market for a case, I might consider just for the novelty since the case is decent in performance. However, I'm not, and I really don't consider cases that costly to start with.
