It's rare, but sometimes the demand curve slopes up, the so-called Giffen Paradox. On Black Friday, the creators of the hilarious game Cards Against Humanity decided to raise their price by $5 from $25 to $30. On his Tumblr, creator Max Temkin recapped what happened:

We called our contact at Amazon and explained the idea for the sale to them. They thought it was funny but were also pretty annoyed - apparently monkeying with pricing on the biggest sales day of the year isn’t as funny to Amazon as it is to us.
Reception
The sale made people laugh, it was widely shared on Twitter and Tumblr, and it was the top post on Reddit. The press picked it up, and it was reported in The Guardian, USA Today, Polygon, BuzzFeed, All Things D, Chicagoist, and AdWeek. It was even the top comment onThe Wirecutter’s front page AMA, which had nothing to do with us.
I was pretty sure that our fans would be into the “$5 more” sale, but I had no idea that it would turn a day where we’d normally be totally overlooked into a huge press hit for the game.
Sales
So how did we do? A little better than last year. We kept our position as the best-selling toy or game on Amazon. My guess is that peoples’ buying decisions just weren’t that affected by $5.
The interesting thing to note is that we got a nice lift in our sales the day after Black Friday (“Regret Saturday”). That might be from people who were waiting to buy the game until it came back down in price, or, more likely, those are sales from people who heard about the game after our Black Friday press. Not bad for an ad that paid us to run it.

When they say any PR is good PR, what they mean is that sometimes it's good to just break through the noise, regardless of why, especially if you're a smaller player. In those cases, the economic benefits from increased awareness outweigh any downward sales pressure from the negative PR since not enough people know about you anyhow.

In this case, it worked even better because Cards Against Humanity is already a subversive brand. It's not for nothing their tagline is “a party game for horrible people.” While I don't think this would hold in the long run, it was a fun one-day stunt on a day that was otherwise a torrent of deal spam and indignant tweets complaining about the commercialization of all that is sacred.
