ETA - Update - It appears that the thanks to the efforts of
@dave30th that Berkeley have changed the donation page, which have been redesigned and now work as a rational person would expect.
----------------------------------------------------------------------------------------
When I clicked on the link in Andy's first post in this thread the only button I could see was 'give now', I clicked on it and got taken to
https://crowdfund.berkeley.edu/project/20159/donate
This page has a text box at the top, with a greyed out 100 in it, below that are a series of radio boxes giving amounts you wish to donate - with text like
Contribute $10
Unlimited
Thank you for your gift of $10!
so I clicked on one, got through the payment process, only to be told I had donated $100
Normally on donation pages the text box is for those who want to donate a specific, or large, amount, and it is overridden by the radio boxes.
I have no idea what a 'perk' is in this context, and Berkeley have in the past done things 'differently' than anywhere else I have ever donated to - so as far as I was concerned I'd selected the $10 donation, filled in the card details, it should have taken $10.
Why on earth would they have almost all of the page for 'perks', whatever they are, when the point is to raise money?
@dave30th did tell me in PM that the front page had amounts to donate, and these did work correctly, but due to the screen resolution I am using none of these were visible, just the 'give now' button was visible - so I clicked that.
