A few Effective Altruist organisations have launched a campaign asking VISA to waive card processing fees on donations to registered charities. More details about the campaign, including a link to a petition, can be found here.
This question asks:
[Short Fuse] Will the #NoFees4Charity campaign succeed in getting VISA to significantly reduce fees for charitable donations?
The campaign will be deemed to have "succeeded" if, by 15 December, VISA has publicly announced that there will be a reduction in fees of at least 50% for charitable donations. Note that the request is for fees to be completely eliminated, however a substantial reduction is still a "win" in a meaningful sense.
A statement by an official VISA channel, including social media platforms, for example @VISA, will be sufficient for resolution.
