Do you ever pay more than the minimum when buying Humble Bundles?

Used to, now I donate extra to charity or publishers, it depends

sometimes, really depends on the contents and the charity.
most of the time its the minimum though for the tier I desire
if I feel the bundle is to cheap for what it contains and want to pay extra to publishers, or I just want to give a good donation to the charity attached to it.
sometimes I pay extra for the guilt I feel from super early bundles where you could pay a penny... and you know they lost money on said transaction.

I don't have much time to play games myself, so most of my purchases were for donating. However, this was years ago.

In more recent times I barely bought a bundle because most of them are pretty expensive, especially compared to a more treasured period in my memory, a period when Humble always had actual bundle tiers and quality games even in the less expensive bundles, not just 6 identical increasingly expensive tiers of basically the same stuff.

I still remember people on this forum worrying when IGN purchased Humble in 2017 and IGN crossing their fingers and promising they won't interfere with how Humble works.
They didn't - at least not radically changing anything. They just slowly pushed the envelope over multiple years, charging more and giving less, making stupid changes that nobody asked for like the Humble Monthly to Humble Choice thing.
You used to be able to choose how much of your donation goes to Humble. Now there's an obligatory threshold you can't go below. Kind of gives their whole game away (no pun intended, lol).
Nowadays I'm pretty soured by all of this and I don't feel like giving them my money just because a portion of it goes to charity. I'd rather donate directly and get my games somewhere else.

i don't really buy many "normal" HB Bundles anymore most of the time if i do i will buy the $1 tier if there is one like the resent Capcom one - so doesn't matter to me but i never paid more than the minimum as i don't have unlimited money

I'll be honest and admit I see bundles first and foremost as great deals on games included. I always set HB's cut to the lowest, and depending on the mood, I'll boost either the developer/publisher slider, or charity one.
I'm also waiting until it'll be more financially viable for me to actually support a charity. But when that time comes, I'll probably simply pick one of local ones I can check out and see if they actually do good stuff with the money, so that it doesn't go to waste.

Yes, I used to. Back when there was still a $1 tier, beat the average, choose your own charity, no minimum percentage for Humble...

Only once I miss clicked and gave HB more than they are worth

No, I tend to pay the minimum. I donate to charities on my own time and try to buy stuff off Itch so devs can choose their own paycut if I can, so I don't think of Humble as my primary way to support either of them.

I will adjust the amounts I give to the specific game companies and Humble if I can. e.g. if I'm buying a bundle mostly for three specific games in it and not planning to play the others, I'll adjust it so they're the only ones who get the percentage set aside for the developers.
